It is true that Phi Sig was the first sorority back at SFSU after the "kick off" and we have now been there for 23 years as of this Sunday.... HOWEVER...I wouldn't give us credit for creating a greek system... the Alpha Phi Alpha chapter at SFSU is about 6 months older than my chapter.. (hence the Alphas are the first "greeks" at SFSU, making Phi Sig the first "sorority") and we didn't call the AGDs or the A phis or Pi Kapp or Phi Tau and tell them to come....
It takes ALL chapters to make a greek system, A-Phi, AGD, Pi Kapp, Phi Tau, A E Pi may not have been first... but they all do their part to keep greek life going and that takes alot more than trying to start a chapter. I thank you for your kind words about Phi Sig though... although I *think* you're giving us a bit too much credit...
