Questions for Newbie

[smugirlnow]

Hey everyone.. this is my first year at SMU I transferred in as a sophomore. At my previous university I did not rush because it was not a big greek life but i am pretty sure I want to rush in January. I am thinking of either theta, Kappa Kappa Gamma, or DG.... can you guys give me some of your thoughts on the 3. Also I have no idea what the process is... how do you get started, find a sorority, get chosen to be in one and what do i need. I read somewhere about letters of rec... is that true? Also do i need to know someone in the sorority... thanks for the help... i am very confused!
