It's snail mail until much later in the season. I did EDP and they said we'd "hear back" on the 1st, after waiting all day for the mail, no letter. I called and they said they just had to send them out by the 1st. That's probably what's going on with you guys. They probably sent them out today and they will be there in a day or two depending on how far you live from Morgantown. Hang in there, I know how much it sucks to wait even more!
Annnnd I just read the rest of the thread haha. Looks like they're doing something new this year. Don't fret about the waitlist. Most people are put on it. I'd bet at least half my class was on the waitlist. Just send in 2-3 updates over the year and hold out for May. All hope is not lost! 🙂
