meeda-
i rotated at harvard, and it was a huge pain to organize. the ortho dept is great, very helpful, but you have to apply through the registrar as a visiting student. they are very much "we're harvard and you need us more than we need you. i applied the week they began accepting apps for a rotation in sept. i had to call and email continuously for months (they won't tell you anything till their students are situated). finally, three weeks before (they're supposed to tell you 1-2mo before) i called the ortho dept and said, "i really want to come rotate, but if i don't buy a flight today, i am not going to be able to afford this, etc". they made some calls and i got my info. throughout, the registrar's office were absolutely atrocious. if you do get it, be prepared to work your butt off. it's a great rotation though-- i learned a ton, got honors and a rec.
cheers.
