CrimsonTide,
First of all, when you spoke of "rep's", were you talking about reputation? If that's the case, when rushing sororities, keep an open mind.
Attending their events is a good chance to learn more about these organizations and to get to know "what they're all about".
I know this response seems vague, but please go and visit Barb's (PnguinTrax) informational Recruitment FAQ. She provides a great deal of information regarding NPC recruitment. I'm going to assume that most (if not all) NPC sororities at UA have websites, and usually they have contact information on those pages. Perhaps those will be more helpful.
