what the heck goes on during rush??!?!

[JMUduke]

Ok...I am sure all the questions I have probably are covered somewhere, but I havent been able to find all them yet, and I am still relatively confused about the whole rush process itself. I go to JMU, and I want to rush, yet I have no idea the differences between NPC/NPHC, a national sorority and a local, informal/formal rush, the whole process of recruitment (how do i get recruited? and signing up? do i sign up for all or only a few??), rounds/pref. parties, what goes on at the parties (chatting with sisters and getting to know them? no interrogations like on 90210??)...ahh im a bit overwhelmed, i originally thought this whole process was fairly uncomplicated! well...let me know if all these questions are answered somewhere else so i can go find it and read it! besides that, I am very excited about learning about it, I cant wait to rush!
thanks
