Alright so I wouldn't touch the greek system with a ten foot clown pole, but that's just my opinion. I know greeks that are cool guys/girls and more power to ya if that's what you want to do.
If you are greek, the rest of the student body is going to stereotype you, just a fact of life because sadly there are always going to be plenty of guys that live the stereotype and they are always the most prominent greeks around.
However like others have said the most important thing is to feel comfortable where you live because, well, you are going to spend a lot of time there. I'd recommend living in the dorms for at least a semester if not your first year just to see what its like before moving in to the house.
I was recruited by a contact I knew before college. I moved out after a year and a half, mostly because I was having some personal issues, but I liked living there, and I'm very glad I decided to do it. Definitely worth a try, at the very least.
Yea this happened to me by a friend of my sister's and he kept me on the phone for nearly an hour and a half before I got really pissed, we don't really speak anymore.
BTW if you ever meet someone in Sigma Chi, be sure to pronounce it Chai as in Chai Tea, they love it
