*hugs binks* Oh God, girl...I know JUST what you are going through! Right now, my chapter is at 17, and we've gotten the "shape up or ship out" message from Nationals. I'm terrified, just as I imagine you are. I can't offer much advice, but a lot of sympathy. I'll be watching this thread, and maybe as the year starts we can offer what worked/what didn't advice for each other!
Another thing........I have come to the realization that I would rather my chapter go down in dignity (after 79 years!) for pledging the right girls & having small numbers than to get shut down because we have dead weight. My chapter is going to stick by this in the coming (as in 3 days from now-eeks!) semester.
I'll keep you girls posted.
