My DD printed out a copy of her email LOA and sent it along with her Nomination application. She will also bring a copy of the email to her interviews. When my DS got his LOA 4 years ago it was snail mail and at the bottom of the letter it stated that a copy was being sent to his nom sources.... this leads me to believe that USNA will notify nom sources.I have read that I should notify my nomination sources of my LOA. I have also heard that admissions does it for you. Can anyone comment on this?
