I'm really impressed with these girls - there is a chapter on my campus, and while it is definitely not something I would ever be interested in (it's not really my religion), I have to give them respect. They are really hardcore. (If sometimes a little harsh toward 'the rest of us', lol.) Check out their chapter website:

This is another non-NPC national that GT has on campus: Alpha Omega Epsilon - a professional and social engineering sorority. They have 21 chapters and colonies.
