I didn't post that I had strong LOR's, but I know for a fact that I do have at least one because my recommender sent a copy of it to me. I really think she did it just to prove it was done as it was late, lol. However, I read the letter and it was outstanding! It actually brought a tear to my eye because I didn't realize she felt so strongly about me and my potential.
I do recall attending a panel once where professors say they have ways of communicating with admissions committees through the letters whether they should really consider certain applicants.
