A physician I work with is retiring at the end of June and loses all access to his email address, and he has no personal email address. He's been out all of June due to a family emergency with no Internet access, so it's looking like there's no way for him to be able to submit the letter. If I can get another physician to submit on this one's behalf, would that be acceptable to adcoms? Is there anything they should do to make it clear that they are submitting on behalf of someone else?
