I was under the impression that Alabama had opened for expansion when DPhiE presented in 2011 and then closed. I didn't think they were still open. But idk.
There are still some groups who could/should be back at Alabama

but hopefully sometime soon
As far as large chapters go, well, our house was built in 2005 I think, and around that time, total was in the mid 90s, in 10 years, total has come to around 200 and PCs are growing every year, with more and more girls going through recruitment. When I was there, we were towards the higher end, and I still knew every single one of my >160 sisters. I can't imagine being in a group that only had 20 members total. Different strokes I suppose. The only issue is house size. Because growth happened fairly rapidly and I guess no one thought the future would be like this, we now have a new-ish house, that's too small to accommodate us.
