Thanks for your replies. It was a letter from the USNA saying she had received a VP nom. Our DD decided the Navy wasn't for her, and it was early in the process, so the Navy portal didn't become the central part of our lives like the ASAFA site has become! As a result, we don't know if that nom was reflected on the Navy Portal.
But your comments are consistent with our thinking; the Candidates learn of their VP nom status in the ~Feb time frame. The Navy communication must have been an outlier.
Thanks,
Scott
