there's still hope for everybody!!
i got an mid-sized manila envelope yesterday! contained an acceptance with 2 (brief) hand written notes from the dean and somebody else.
however i previously emailed them around tuesday on the 16th to check my status, and received a prompt reply the next day saying they created a "letter" on the 12th and mailed it on the 15th... i was really nervous and was already accepting a waitlist/rejection because 1. people on this forum have been saying that if you didn't receive anything early dec. then it's probably a waitlist/rejection so i was sad this whole week. 2. the email said a "letter" which i interpreted to be 1 piece of paper with a rejection.
i heard they are processing letters each week, so i'm guessing they may send out something this monday. good luck!
oh had my interview in november btw.
