Encourage your friend to go into recruitment with an open mind so she can get the general feel for herself. If she hasn't done so already, go to the different sorority websites and learn some facts about each one so that she's armed and ready with stuff to talk about during the rounds.

If it's discussion on individual reputations you're seeking, I doubt you'll get much luck here.

There are lots of Southern California sorority women here who know a lot about Greek Life at USC!
