thanks dmbmd...I'm still debating what I want to do. I liked both BU and Tufts and hate that I have to decide between them, but I am ecstatic to be in this position. I'm still holding out for UMass but am going to have to send in money to one of these two schools by week's end. So I have some thinking to do...I find BU and Tufts to be quite comparable and can't force myself to pick one right now, but I suppose I have to soon!
Once I got the waitlist letter, I wrote an email because they said that was the beest way to contact them, but I got an automatic reply saying that the address would not be monitored because someone was on vacation. So about a week later, I wrote a letter and mailed it snailmail saying essentially the same thing...Good luck to you, but if you haven't, I'd advise writing a letter to let them know you're alive and interested!
Good luck and I'll let you know what I decide, if I ever do decide!
