I don't understand how NPC sororities work

[Aduladi]

I pledged at a school that has BGLO's LGLO's Multi-CulturalGLO's local GLO's and NPC/IFCGLO's, so there were enough organizations to sufficiently distract me from paying close attention to what other Greeks were doing beyond programming. I am now the advisor for my sorority's chapter on a campus where there are ONLY NPC/IFC GLO's and my Multicultural Sorority.

Recently something that I have never seen, happened on my campus and I am at a loss-somewhere between confusion and sadness...

The national board for a sorority on my campus pulled the charter for a sorority without any discussion with the Greek Advisor or the chapter, citing low membership numbers (at 48 members, they had the largest charter and the highest combined GPA of ALL Greeks on campus).

I would like to use this thread to understand these organizations and how they function (rush, and other rules that govern their chapter activity).

Soo... if anyone wants to take some time to teach me that would be great. I think I'd like to start with how the Nat'ls can just walk in at the end of a school year in which a chapter JUST initiated a pledge class and take the charter away without any regard for the great things the chapter might be accomplishing on campus.

Thanks-I look forward to some good info!
