Applying to colleges? Here's some advice about Facebook from the book "Get Into College" (Hundreds of Heads Books, www.hundredsofheads.com, $17.95), straight from people who've done it:

"There are certain things you should keep private and not put on your MySpace or Facebook profile.

"I had a few friends that had colleges contact them through Facebook. One example was this girl who decided to go to NYU, so she joined the network on Facebook but hadn't told the other colleges that she wasn't going to attend.

"Another college she had gotten accepted to messaged her and asked her if she was in fact going to NYU. I think as social networks become even more popular, colleges will use them more to learn about an applicant. Especially as it becomes increasingly competitive to get into a selective school, I would advise people to hold off putting up risky pictures — at least until they're enrolled."

— Anonymous, University of Southern California"Facebook was both a comfort and a nuisance in my college application experience."It was a great tool for seeing and learning about the people in the schools I was applying to, and joining groups with other students in my situation."But I would strongly recommend that high school students limit how much they let Facebook influence their final decision. The only way to really get to know a school and its student body is to visit and talk to them in person."

— Casey Heermans, University of North Carolina at Chapel Hill"Don't post pictures of yourself drinking/naked/etc."
