My campus doesn't have a quota, but we also don't have a Panhel (we are on Greek Council, though). About 6-7 years ago, my school basically let the Greek system go to hell, and it's just now starting to rebuild. There's only one other NPC sorority on campus, and they only have about 3 members.
We are late on getting bids out because our VP of Membership was hurt in a car accident
