A number of my friends and business colleagues use Skype and I'd like to be able to chat with them while traveling, but I don't know their Skype account names. Is there some directory of Skype names and/or some best practices about how to search for someone in the Skype universe?

This is very weird. The SMS messages I get from Google Voice are always from 406 numbers. What's 406 and why is it always from the same place?

I'm just starting to get up to speed with Google's slick Google Voice application and have heard that you can use it to make free or at least pretty darn cheap international calls. I'm psyched! My brother is in Sweden and we rarely talk because of the cost of long distance. How can I gain access to the cheap international calling with Google Voice?

I've been hearing on and off for a while about this slick new answering service I can sign up for called Google Voice. A part of Google, obviously, but I haven't figured out how to sign up for it or even how to learn what it is. Can you enlighten me?

I'm always on the go and seem to constantly bump into interesting and weird situations. I'd love to be able to take those photos and share them with my friends on Facebook, but I don't know how to connect my phone with my Facebook account. Can you step me through this entire process, please?
