I have a similar problem to that which you wrote about in How to read message headers in Google Gmail: If i have received an email from my friend, how can I tell whether it is spoofed or not?

I know that Google's Gmail service has a spam filtering system, but a friend of mine was also telling me that you can use a "plus notation" to compartmentalize incoming spam too? Do you know what he's talking about?

I've been using Hotmail for years without a problem but suddenly it rejects my password, and when I go to the password recovery option, it doesn't like my zip code or other secret information. I have vital information in my inbox! Can you reset my password for me or tell me the new password?

I'm working with a company that's overseas and they want to send me some contracts via fax. Problem is, I don't have a facsimile machine and going to somewhere like Kinko's and paying to receive their fax seems a bit daft. Are there free fax services on the Web, or at least cheap fax services online?

I'm still trying to wrap my brain around how Google forces you to interact with your email when you're using Gmail and really miss folders. Can I emulate the same sort of auto-filing of messages with the "labels" feature so that messages from a specific mailing list never show up in my inbox at all?

I want to add photos to my blog, and a buddy told me that I can use images from the Yahoo Flickr site. I don't want to get in trouble, though, so can you tell me if there's some way to identify those photographs and other images that are legal for me to republish?

My boss has me working on our company Web site and she wants me to add a box on our "contact us" page that lets people type in their address and at the click of a button bring up a window with driving directions from their location to our office. Is that even possible?

I think I'm hallucinating or something: it appears that I'm getting spam events added mysteriously to my Google Calendar schedule. What the heck? How is that happening, and how can I stop it occurring?

I need to find the sender of an email I received that was a death threat and the domain was @gmail.com. I have contacted the police and fear it will take too long for them to find out any information. Is there anyway you can assist me? The email address was deadlykillers61@gmail.com.

I've been running Memeo LifeAgent on my computer for a few months with very good results, but recently wanted to add a specific folder to the existing network backup and was stumped. How do you add or change an existing backup schedule?

I checked out your Twitter page, Dave (see: Dave on Twitter), and it looks really nice. How'd you do that?

My local newspaper's computer guru recently said that it was possible for a hacker to read what you have just copied into memory. The example he used was copying your password from a text file into a password box on a website. Is this true?

I think we're kindred spirits, Dave. I spend way too much of my time on the Internet Movie DB and would like to cut out a step: is there any way in Firefox that I can have the little search box on the address bar go directly to IMDB?

I'm using Powerpoint 2007. WHY CAN'T I CHANGE ONE SLIDE COLOR BACKGROUND WITHOUT IT CHANGING ALL THE REST??? Sorry, I'm just a little frustrated. I've looked online at everyone's comments, done the tutorials online and no one is commenting on 2007. If you right click to change background colors the ONLY option is Apply to All. Am I missing something. Please help!!!

Today I tried to use Mail to send an e-mail to someone. Everything looked fine until I got an alert saying CANNOT SEND MESSAGE USING THE SERVER SMTP.MAC.COM. I have the option to choose another server, however, the drop-box does not have my account as one of the options. What the heck?

I'm a big fan of Google's Gmail service, except there are some things I can't quite figure out. For example, some of my mail is routed into folders (well, label bins, whatever they call them) and I find myself paging through thousands of messages to identify those that are unread. Also, can I search through my chat history to find specific things?

I'm wondering if I can create a group within my google contacts and make these group also available to other google users. I realized on your website that you are a google guru - so I thought I give it a try and ask you!

I often have long, complicated mail threads in my Google Gmail account and get frustrated when I want to respond to the person sending a particular message, but not the rest of the people on the list. Is there some snazzy shortcut for doing just that?

This is weird: my friends are telling me that when I send mail from Gmail, the return address is to googlemail.com, not gmail.com. Have I had my Gmail account hacked or something?

Don't tell anyone, but I've started downloading music and video files from peer to peer bittorrent networks, but the words that they use are baffling me. Most importantly, what does "nuking" a download mean?

Hi Dave. I'm an inventor and I want to do some research on competing patents without paying major bucks for a lawyer. Is there some sort of site where I can poke around and identify potentially conflicting or competitive patents here in the US?

I've read about "Google Profiles" and am definitely interested in figuring out how to set up my own profile. I'm still not entirely sure why I'd bother, but can you at least tell me where I'd set one up within the Google empire?

I've moved into a new position at work and am now responsible for editing press releases to ensure they have proper grammar prior to their release. In the past, I've seen people work with Microsoft Word such that any changes they make are highlighted on the screen, easily tracked, but I have no idea how to do that. How do I turn it on?

I want to download an mp3 recording that a company has put online at the site 4shared.com, but every time I click on the "download" link, it actually opens up another window and plays the $#@$@# file with no download possible!

Hey Dave! There are all these great deals on computers this Christmas season. How do I know which computer I should buy?

Saw your note about Yahoo IM "spim" and I too have a couple of jerks who are sending me this junk. Can you tell me how to block them so I don't hear from them again? Thanks!

I got a request to have someone connect with me via Yahoo Messenger, and though I didn't recognize the email address, I said "yes". Next thing I know there's a message from them that's full of sequences like <#43243>. What does it mean?

Over on your business blog I listened to your recent audio recording with Rob McNealy of Startup Story Radio and was quite impressed with how cleanly you chopped out about 20 minutes of the original audio to present a version that's more tightly focused. How the heck did you do that?

I need to get a multi-user chat going for a project I'm involved with but we all dislike Yahoo and its IM client. I heard that Google just introduced group chat within gchat, a tool I do like. How can I add two more people into my chat window so that we can all see what each other types?

I read your article about whether Limewire is legal or not and think I understand what you're saying. My follow-on question: how can you tell if a file is legal or illegal?

Now that I've gotten into the world of Twittering, short one-line status updates on what I'm doing and where I am for my friends, I am curious if there are any additional secret capabilities in Twitter that I should know about?

Google makes a big deal about how you should keep all your email when you're a Gmail user, because it's easy to search through your archives, however big they may get. What I can't figure out, however, is how to search my deleted email!

I just noticed that one of the actions I can take on a discussion thread in Google's Gmail service is to "mute" it. What the heck is that? Something to do with audio playback, perhaps?

Dave, I bought the Canon PIXMA Pro9000 color printer about two months ago and am still trying to decide whether I like pigment inks.  Not my first try with a pigment printer as I've also got an Epson 2200.  I'm okay with the Canon, but I do think it's slower.  The color accuracy I've seen is better on matte papers like photo rag than on the semi-gloss papers.  I've been a little less than impressed with the Mac OS X drivers and would really like to know about other people's experiences with the Canon printer so I can compare my own results. Do you know any other PIXMA owners?

I have read lots of articles about how to constrain search results on Google by domain, by site, and even how to group words and include "negative" keywords to ensure that I don't get spurious matches. What I haven't figured out is whether there's any way to constrain my searches by date. For example, to just find material that's been updated or indexed in the last week. Doable?

I have just set up a wireless connection at home - whenever I log on it says that the connection is unsecure - how do I secure it? I have a new Toshiba Laptop and a Phillips Router. I saw something about a WEP key....where do I enter this?

I remember a snippet of a song from years and years ago, but have no idea who sang it, what song it was, or even what "genre" of music or era. Can I dig it up with Google or some other tool? The phrase was "wrapped up like a deuce", I think.

I am concerned regarding eMail that I send to a variety of people. I know that they ARE receiving my letters or information....However, I receive eMails telling me that the messages failed. I know for sure that they have not. What is going on?

Even though I use a variety of calendar programs, I still forget events! Darn it! Since my boss wants me to use Google Calendar instead of my current solution, I'm wondering, is there any way to get Google Calendar to send me event notifications via SMS text messages? That'd be cool...

This is weird: I think I got some spam from Picasa, the popular photo hosting service from Google. Is that something you've heard of before, Dave? And what can I do about ?

Am currently in the uk and here the domain for gmail account is @googlemail.com. I recently created a gmail account and i was wondering whether theres a way to change my address from username@googlemail.com to username@gmail.com? I know that whether you write username@gmail.com and username@googlemail.com get delivered to the same inbox..but still want to change the domain of my email add! :))

I am anxious that I've been a victim of identity fraud: I just got an email from some mortgage broker indicating that I'd been approved for a refinance of our home, but I didn't apply for anything like that! I figure it's some scam, but they showed the amount of our original home loan and that's made me jumpy. Am I a victim or what?

I think that Google's "I'm Feeling Lucky" button is great fun and want to have that feature on my site, but before I start digging into any sort of coding, can you tell me, how does it work?

Is it true that it is not secure to subscribing to my Gmail Inbox RSS feed in a RSS reader, say Google Reader or newsgator? I've heard that by doing so everyone can see my e-mails...

Hi, can you please send me the procedure how to redirect the mails from Gmail account to Yahoo account?

I use AOL occasionally to test things, but refuse to download the AOL software as it's bloatware and always seems to screw up my PC. So I go in through AOL.com. But using that, how the $#@$@ do I change my account password?

Dave! I'm a big fan of Google Gmail - like you are - and have gotten most things figured out, but I'm wondering if you can tell me how to set up a vacation autoresponder so people know when I'm on a trip?

I'm a big fan of Google Calendar except I am a bit stumped about how to create a monthly event that repeats based on the day of the week. My parenting group meets the first Thursday of each month, but I can't see how to capture that in Google Calendar. Is it possible?

Hey Dave! How does secure SSL actually work and if all these sites are using this much vaunted https/SSL security, how come they still get customer data ripped off?

i have an issue. My daughter is getting im'ed by someone not on her buddy list. How do i stop people not on her buddy list from joining a chat she is part of and how do i find out the identity of thi person?

Recently I asked a friend if I could have a copy of a cartoon graphic on his site. He asked me if I wanted it in "vector or bitmap format". I thought the formats were things like .gif and .jpg. What do "vector" and "bitmap" mean?

I've been running in Hotmail for a long time, but just recently saw a friend log in and was amazed to see that he has a three-pane view, with a preview of the message on the same page as the list of incoming messages! I want! How do I switch?

I'm wondering if there is a way to save the google safesearch preferences for users in a mac os x server environment. We have kids that we would love to have search using only the "strict" filtering. Is there a way to set that preference in os x server? Thank you very much!

I know that I can delete entire discussion threads in Gmail, but what I'm wondering is if there's a way to delete individual messages in a thread, not the entire thread? Y'know what I'm talking about: sometimes discussions start out focused and then get sidetracked...

I've been reading about the newest wireless standard called 802.11n and am unclear whether it's a smart upgrade or not. My geek friend tells me that it's not an "approved" standard and that there's a risk that what I buy might not be compatible too. Is that true?

I need a better way to help my friends gain visibility when they blog about something cool that I think is of general interest. I've heard Digg is cool for this but don't know how to "dig" an article?

A few pals have told me that they've "friended" me on the bookmarking site Digg, but I have no idea what they're talking about. Since they've listed me as a friend, I figure I should list them as my friends too, but I don't know how to do it. Dave? Can you help me out?

Every so often I get an email attachment and double-click it to open it up on my Mac. It opens up fine, I make edits and save the document, but then when I quit Word I can't find the $#@$# document on my system. What's going on and where are the documents I've edited?

This is baffling me: I have accounts on quite a few different Web sites and most of them just ask me for my account and password. Some of them, however, have a handy checkbox labeled "remember me" but now I just signed up for one that has a checkbox for "public terminal". What does that mean?

I dunno if this is legit or not, but I recently bumped into a note from someone claiming that there's a secret email address at Yahoo.com that lets you sneak into a backdoor and recover any account password for any account on Yahoo. The address was "recover_pswd@yahoo.com" and it sounds too good to be true. Is it?

I've been trying various proxy servers to get to MySpace from school and sometimes they work for a while but other times they don't work at all because they're banned or blocked. What is a MySpace proxy server, how does it work and why would they work for a while and then stop?

I simply want to forward a joke to several people in Gmail, but can't figure out how! If I click on the drop down by reply, then it opens up the TO: In regular email, you click on the TO and it opens up the address book and you can then select whom you want it to go to.

How do I get my address book open, select the people I want this to go to
and have them appear in the to window. I have been reading on the internet and talking to people, and we are all having the same problem. This does not seem to be a user friendly email. I generally don't have problems adapting to new software.

This is such a simple question I can't believe I'm asking it! Being a huge gmail fan since switching from hotmail I can't find out how to save the sender's address to my contcats list other than copying and pasting the address having gone to contaxts and create a new contact. Surely the good people at google have a one click solution for me that I just can't find! Your help is greatly appreciated.

I have high speed Internet through my cable provider and am about to buy a palm pda, not one that has a phone in it though, anyway it says it can get on the internet with a wi-fi connection and has the wi-fi stuff installed on it. I want to know if you can use wifi with high speed wireless cable internet or what. and what is wifi, and where can you find it??? Thanks
