That was my understanding as well. However, at my interview in September my group was told accepted students would receive an email on October 16th and a packet in the mail later in the week. Waitlisted/rejected students would receive only a letter in the mail. So I think myself (and maybe everyone else on this thread
) are worried that since we didn't receive an email yesterday it means we have been waitlisted or rejected. Of course, it's also possible they are simply running a little behind and acceptance emails haven't been sent to anybody yet.
