I brought this up in NLH's rush thread, but I figured it might be a good idea to bring it up again.

When Rho Gammas advise PNMs to use caution with Facebook and MySpace, why should it be limited to those sites? They should add GreekChat and CollegeConfidential to the list as well, IMO.

Rush threads are okay, but it's definitely not worth risking your chances of a bid.
