I work with a girl who was in an NPC at Buffalo. She is a recent graduate and knows many of the people who will be shown. She's going to hold viewing parties and give us the low-down on people, Greek Life there, etc. I'll let you know if I hear anything scandelous!
Also, she mentioned that she spoke to some of her sisters who are still there, and even if they were at an all-Greek philanthropy or something, MTV was asking everyone to sign waivers to be shown. Obviously her NPC group refused to sign. And she mentioned they didn't hold any events with the fraternity while the show was being taped.
