I also just got this, but I definitely was not YP'ed:
"The Committee on Admissions has reviewed your application and has placed your name in a special group within our Preferred Waiting List.
Generally, applicants on the large Preferred Waiting List are those that we would like very much to include in our first-year class. However, due to the large volume of highly qualified applicants, the Committee cannot extend as many offers as it wishes. As a result, the Committee has been forced to make some very tough decisions, and your application was especially difficult."
No trajedy though, I only would have attended with a good chunk of money (which I wasn't going to get anyway). I'll be withdrawing, so best of luck to the rest of you!
