I had all of my profs submit through interfolio and I encouraged them to upload their letter to I could get them asap. Anyways, I am now worried that my profs did not add an electronic signature and that medical schools will not accept them. My question is, does interfolio prompt the profs when they are uploading to add a signature or remind them to? I know I could just ask the profs myself but two are on vacation and the other I am not sure where he is so I figured it would be just as easy to ask here.
