We're not really having problems with any Greek group, specifically...they're just not very open to the idea of us affiliating with an NPC. If we had insurance, we would be able to participate in more campus Greek activities, but as of now insurance is just too expensive. We participate in informal rush, which I like better than formal rush anyway.
Each year, it seems that we are more accepted so, hopefully, eventually we'll be able to affiliate with an NPC and have the same rights as any other Greek on campus.
