Interesting topic!
1. What sororities and fraternities are on your campus?
Lafayette College (from 1997-2001):
Sororities: Alpha Gam, Alpha Phi, Tri-Delta, Delta Gamma, Kappa Kappa Gamma, Pi Beta Phi
Fraternities: Chi Phi, Delta Kappa Epsilon, Delta Upsilon, FIJI, Kappa Delta Rho, Phi Kappa Psi, Sigma Alpha Epsilon (gone Spring 1998), Theta Chi (gone Fall 2002), Theta Delta Chi (gone Spring 2001), Zeta Psi
2. How many people are in your chapter?
When I joined, there were 14 active sisters. When I left, there were about 36. I think there are about 33 right now (our website is down right now or I would get an exact number). Total is 75.
3. Do you have any rivals on the campus?
I'm going to be Panhellenic and decline to answer this question.

Recruitment has been pretty cutthroat over the past couple of years, so pretty much everyone competes for girls.
4. How do you think that people see you on your campus?
Hmmm...this varies. We were usually seen as one of the small chapters, which is true. I heard a number of untrue rumors just because we're small and people don't really know any of us. Once people get to know us, they usually think we're normal and easygoing--not the stereotypical sorority girls.
5. Who do yall mostly associate with?
I was (actually, I guess I technically still am) a Theta Chi sweetheart, and a lot of us hung out with them. We also used to hang out with the Phi Psi's a lot. I'm not sure who the girls hang out with now.
