Just to clarify, the Farmville Four were: TriSigma, ASA, KD, and ZTA.

I know Sigma Sigma Sigma's Alpha chapter has never been closed (founded in 1898) and is still going strong. But I'm not sure about the other three...
** Sigma was the first NPC group with chapters in Alaska (Zeta Mu at the University of Alaska Fairbanks and Eta Zeta at the University of Alaska Anchorage)
** Sigma was the first NPC group to have a chapter in Europe (Eta Mu in Germany)
** Sigma was one of the first to have a hearing-impaired chapter (I don't know if we were first, though)
