Case Western Reserve University votes to allow a 5th NPC sorority.

NPC groups currently at Case:
Alpha Chi Omega
Alpha Phi
Delta Gamma
Phi Mu
I do not know if there are any other NPC groups who have ever been at that campus. (I know that Alpha Gamma Delta has never chartered a chapter there, but don't have the info for other orgs.)
