Okay, I can finally update. The COB went a lot better than anyone expected. We had 26 women show up! We had them all fill out information cards, and we all ate banana splits. ZTA's advisor and our CCD talked to the women about Greek life and encouraged everyone who received a bid to accept it.
After the COB was over, both sororities went to their respective chapter rooms to vote and deliberate. We ended up giving out 11 or 12 bids (not sure which), and Zeta ended up giving out 3, which was the maximum number they could give out, as they are almost at total. (Unrelated tangent--while we were waiting for the Zetas to finish voting, my sisters had a candle pass for me, because my boyfriend lavaliered me the night before! I was really happy!)
As of right now, I'm not sure how many people accepted bids from either us or Zeta. I know one woman for sure accepted a bid from us, because I was standing there when she signed her bid card (

), but other than that, I don't know. I'll be sure to update when I hear a definite final number. All in all, our joint venture seemed to work out pretty well! Thanks to everyone on GC who supported us. *Happy dance*
