I must say you are not alone. I was waitlisted since Feb, and still waiting. I sent two emails this week, one to the program coordinator and one to the program director, no reply. I tried to tell myself this is it, but I know I wouldn't let it go until anything official arrives. Big hug.
Just checked umass amherst website for no reason. The application status turned from under review to update pending. Let's see what's going on next few days(didn't get interview like others, I already take it as a rejection already though).
I've recevied a letter from University of Arizona on friday morning(thursday night in the States) and been told I was on the waitlist of fiction. Getting my foot in the door i guess?
By the way, I am wondering what's draft and NWP means, it would be great if someone could explain this to me:D
