I tried searching for previous threads on this but couldn't find anything, so please forgive me if I'm asking a question that's already been answered.
How come they're voting to expand when a sorority just closed so recently? Was it due to numbers? And as aopinthesky asked, how many chapters are at total and did they all make quota?
As for possible groups, I agree with ZTAngel - Phi Mu would be a good one. I think Sigma Kappa or Delta Zeta would also be good choices.
And of course I think SC needs another AZD chapter.
Regarding the alumnae base...Clemson's not too far from Charlotte (what, within 2 hours?)...there are a LOT of strong alumnae chapters here (for any group) that could help out as well.
Also - Clemson is not far from Western Carolina (within and hour and 1/2), and AZD and Phi Mu are both strong there...so if either of those groups were a possibility they would be able to contribute.
