Outing myself as a total geek, it's an interesting read! There were a few things that are really clarified for all the discussions we've had here about how it works.
One in particular is about upper class quota. I've read here several times that a chapter is not obliged to participate. However,
"Once a Panhellenic has voted to establish an upperclass quota, individual chapters may not opt out of accepting those women without consulting their inter/national organization, the FSA and the RFM specialist before recruitment begins."
So while it may be true that they don't HAVE to participate, they better have a reason that headquarters will accept. And we all know headquarters wants us to maximize membership, so "we think we're too cool to accept sophomores" really isn't going to cut the mustard.
I'm definitely going to keep this at the ready for all the questions that come up starting in about 2 months!
