i'm still waiting on one as well. i finally got a diff prof to send one in so that at most schools i have the right number of LOR's even w/out the one that hasn't been sent in yet. it's really a pain to know that your appl is being held up simply b/c one person hasn't sent in the letter they promised you they would send in. hang in there and maybe beg someone else to write you one real quick and give them the money to send it priority to every school that needs it.
