Speaking of Elon, I saw this article today.

It appears that Greek Life intends to educate PNMs about what sorority is life is really like and they believe this in turn may lower the number of PNMs going through recruitment this winter. I'll be watching this story to find out more, since the article seems to leave a lot out. As an Elon Alum, I'm surprised they are deciding to go this route over expansion since the number of undergrads keeps growing, which is increasing the numbers of PNMs going through recruitment. There are a few groups on campus who have a history of retention issues, but from what I know, those are for other reasons.
