Congratulations! Just checked, and the letter was there, but they don't want me. They offered some kind of wait-list deal, in case some other students don't attend. It doesn't say if they sent that...
Yes, I am in the same boat, but I probably won't be any help to you. I'm not sure what their acceptance rate is or what criteria they look at the most, but that is what I'm most curious about at this...
