i finally gathered the guts to call my interviewer, and while he said he remembered me and all, he said that there really was nothing he could do/write/call. his part of the app process had been closed, and there wasn't an appropriate point of entry for him. he said just to write them a letter...
on a more general waitlist note, i received the following notice from tufts (which i am withdrawing from) which might be generally applicable:
>>
- we do not rank our waitlist. as ppl withdraw from our class, we monitor the demographic composition of the class (geographical distribution, representation of undergraduate institutions, etc.) and admit candidates form the waitlist who would best balance the composition of the class. during the summer moths, the admissions committee does not meet on a scheduled basis as it does during hte academic year; rather, it meets on an ad-hoc basis, reviewing waitlist applications as needed
