I didn't read the article properly, so when when I saw the headline, I thought G'Town was going to RECOGNIZE a fraternity. I knew about AEPi. Good luck to Sig Ep in their efforts. We have a chapter at Brandeis, where they don't recognize greek life, and it can be tough.
As for greeks, G'Town is the home of the International Foreign Service Fraternity and Sorority of Delta Phi Epsilon....NOT to be confused with the NPC International Sorority of Delta Phi Epsilon
