Hey Adam,
Two weeks ago I wrote a letter to my interviewer who I have been keeping in close touch with (she was a 2nd year and she urged me to write her in March). My letter was basically just asking where I am on the waitlist. I also asked her to reply when she felt that the list was no longer fluid. She has not replied yet therefore I can assume that they have not solidified and began to draw from the waitlist.
BTW You should read one of the recent questionaires at Interview Feedback on Buffalo. The guy says that Dr. Paroski informed the interviewers that it is quite possible that EVERYONE will receive a call this year??? What are you're thoughts?
