Like to reference your friends - with links to their own Facebook profiles - in your comments and Wall postings, but hate that the default on Facebook is their first + last name? Turns out there's a neat way you can sidestep that and still leave those helpful links intact...

I rowed with my girlfriend and posted something terrible on my status. Now we're friends again and I can't delete it...No option, remove or delete buttons...? HELP!

Dave, Help! I posted a status update to my Facebook Wall, then realized I didn't want it there, but while I can see the "hide" buttons on other people's entries on my page, and I've seen "delete" buttons on people's comments on my earlier Wall postings, I can't see how to delete my own posting. Help! This is important!!

How does Facebook make money, Dave? I mean, seems like every time I log in there are new applications from third parties and more friends to connect with, but I never pay a nickel. In fact, the only place I've ever bumped into a request for payment is when I want to send someone a "gift", but that's all based on "facebook credits"? What's the scoop?
