I need help from NPHC groups.

[PhoenixAzul]

I'm a PX at an all-locals school. Our rush is soon, very soon. I just want to know what steps I should tell my girls to go through if they decide that they are interested in one of our NPHC groups? Since all of our chapters are city-wide, how do I find who to contact? Is there a formal recruitment process? I just want to have some sort of info to give them if they decide this is the way they want to go, and I'm kinda not in the know about the system and how it works, so if someone would give me a bit of a clue, I'd be very appreciative. Thanks!
