Our school has a fairly small Greek community:
Sororities:
Alpha Chi Omega
Delta Gamma
Gamma Phi Beta
Theta Phi Alpha
Fraternities:
Sigma Phi Epsilon
Alpha Delta Gamma
Phi Kappa Psi
Beggars (local)
NPHC:
Alpha Kappa Alpha
Alpha Phi Alpha
Phi Beta Sigma
Delta Sigma Theta
Kappa Alpha Psi
Our main problem with expansion is that we're right next to Tulane, and they already have several NPC sororities (I can think of Kappa Alpha Theta and Chi Omega off the top of my head.) I'd like to see a chapter of Delta Delta Delta, Phi Mu, or Pi Beta Phi here. I've heard rumors of a new sorority coming onto campus, but they're all unsubstantiated.
