I e-mailed to ask about the status of my application and got a confirmation from Warren Smith that I've been waitlisted. He informed me that I am at the "middle" of the wait-list, that there's a "good chance" they'll get to me, and asked when I will need to have a definite answer.
I know that the positive tone need not imply more than that they want to keep me from accepting another offer for now, but it is nice to have this information. My other offer said that we shouldn't feel pressured to make a decision before April 15, but that, of course, they'd like us to inform them as soon as we can. What do you think I should say? Duke is my first choice, and I'm wondering if telling him that I do have another good offer but that Duke is my first choice would help me at all.
