I'm in the same boat as you guys. Dr. Z said I was waitlisted, but I never got the paperwork and my AADSAS still says "Invited for Interview (on November 29th)," whereas those that received the paperwork, and subsequently sent it in, had their status changed on there. I'm sure I likely would not have heard anything if I hadn't emailed. Maybe it's a good sign...? We.Shall.See...
