I got in off Duke's waitlist about a month ago, thank God! I got rejected by every other school I applied to (I applied to 13 top schools) other than my backups and the waitlist at Duke. I never got the email you guys are referring to, but I was placed on the priority waitlist. The only advice I can give is to keep sending stuff and checking in to let them know how interested you are. I sent in about 6-7 additional letters of recommendation, extra essays, emails to Dennis every couple weeks, etc to let him know that I was 100% willing to attend if he would let me in. Duke was my first choice, so I'm thrilled. If anyone else got in off the waitlist, I'd love to hear from you. Good luck, all. I understand the waitlist agony all too well.
