So I had a couple professors write letters of rec for me, but there was one who I knew would write me a very good letter (he's written a few for me before). The only problem though, is he didn't sign the back of the envelope that has the letter of recomendation in it. He is on leave from the University for the next month or so...and I'm planning on sending in all my letters of rec in before he gets back.
Do you think it would be a bad idea to still send in this professor's letter (unopened, but unsigned)?? or should I just send in my other two letters instead??
Thanks for the help ya'll!
