panotpijohn, I'd received your email, but I couldn't reply to your address... my mail server said that it couldn't deliver the email, and I'm sorry I wasn't able to reply to you.
I've been accepted into Brown history Ph.D, and I received my official acceptance letter by postal mail. The letters were dated 18 February. Before and after the official letter arrived, I was also contacted by four of the faculty members of Brown history...
As far as I know, the accepted students have all been invited to the mid-March prospective students' weekend, by a grad student who's organizing the visit.
Hope this information helps!
