They've invited three groups to present, Delta Chi, Chi Phi and Pi Kappa Phi. Pi Kapp presented tonight and was the last of the three to go. They had a chapter there for some time, but it closed in '96 I believe.
Currently, they have Kappa Sigma (one of my friends from HS was a brother in this chapter, and a former neighbor was as well), Pi Kappa Alpha and Tau Kappa Epsilon. If you remember, about a year ago (or so) SAE was kicked off campus.
The NPC groups include Zeta Tau Alpha, Sigma Sigma Sigma, Delta Zeta, Alpha Delta Pi and Chi Omega.
Here's a link to their Greek Life page.
I'll update if I hear any news. A decision is expected next week.
