Facebook data

How long does Facebook keep messages, status updates, comments, etc? Is there a nice Facebook client that will let me store my content permanently? I get email notifications, but they contain other people's replies to me, not the stuff that I write.

I'm worried that people have been increasingly choosing Facebook over email.

Do they have no user testing when they design classrooms? The least they could do is make it easy to set the projector's image higher.

Is there an easy way to lift the back rows of a classroom, stadium-style?

If UBC had a vertically-challenged students association, this would be one of their top issues.
