Yeah I mean I get your point but I also feel that using the Facebook group isn't really a good indicator (even though I still can't help but checking lol) I feel like the people that don't have facebook might be very few and some might be admins and older students / faculty as others said.
Also, I hope that they do send some acceptances in bulk because I feel that alot of us just got placed on the waitlist right after the interview and they do prob need to fill up that class soon. Anyways this is just me being hopeful and praying for all of us at this point
