It's great that you want to join a sorority and go through recruitment! The single most important suggestion I offer is to keep an open mind. We say that often on GC, and we truly mean it. First impressions are great, but sometimes you can not and do not get a clear picture of all the sorority options you have available at first impression.
Have you read the 1st Announcement thread in the Rush Forum? Check that out, and here are a couple other threads I think mya be helpful about general information on Sorority Recruitment.

In addition, I have to agree with smiley's suggestion about your user name. I'm clearly not a member of Phi Sig, but I would expect someone with such an User Name to be a member of that sorority. You really may want to re-register with another user name so that no one will think you are trying to be something you aren't.
Good luck!
