I accepted a spot but have not heard anything. I think the mail should be rolling in soon. My first-year friend said that tons of stuff starts coming the end of April or May. They are probably double-checking and making sure they have a full class and that they don't need to send out any more offers of admission to waitlisted people.
I'm getting excited/anxious too! It will seem so much more real when we're filling out the paperwork 🙂
