re: Louisville, from what I can tell, no one heard from them previously, and they sent two simultaneous e-mails around 5:40pm EST, invite and rejects; are there people who applied but did not get an e-mail? if so, then you are on the wait list.
I have a feeling the two emails contained everybody, and there is no wait list; if they need to invite more from the rejected list, they'll probably take those of us who will invariably write back and beg.
good luck everybody.
