So the original post is pretty old, but I'm pretty sure that SGPhi girl is from my sorority (Arethusa -- Sigma Gamma Phi), and as an update, we now have four chapters in NY state, not just three.
http://www.arethusa.org is our website.
We're still considered local, because each chapter is independent and we don't have a national headquarters (although we have a yearly convocation where all the chapters get together)...although we consider ourselves regional. There's a lot of "local vs national" drama/competition at my school and there's benefits to being on either side of it.
