I've never thought about this too much but there were some local organizations on my campus. Some of them were former Nationals (mostly frats) that had lost their charter and weren't recognized by the school. They were still pretty strong organizations and several of them hung out with other chapters that were nationally recognized. There were a couple of Local sororities but I really didn't know too much about them as they were very tiny (ie. 6 members) and really didn't participate in anything with the rest of the Greeks. I know this may sound bad but I really don't understand the point of pledging an organization that is not nationally recognized. At least I know every where I go there will be D*Phi*E you can't say that when there is one chapter of an organization on one campus. I'd love it if more locals decided to affiliate with a nationally recognized organization and become National, especially at SUNY New Paltz where there aren't too many organizations to begin with. But that is all easier said then done, I know. We have TKE on our campus by the way
