Here is a link to the history of the Greek system at the campus.

Apparently they formed as a local in 1985. According to the history there were a lot of locals and then the campus lifted a ban on nationals in 1976. But they also say since then a lot of groups have dropped their nationals or lost charters. Makes you wonder why... Looks like the campus is primarily locals.
Let's just hope they don't sign up for Sorority Life 4 - Think of the PR nightmare that could be if they are represented as "AOPi"!
