I put messages on the other genealogy sites that I am a member of, about the reunion, with the website link. Quite a few people had not heard about it. This may be a impractical, but I thought it's worth a try - A.J. and I are very distant relatives. Is it worth sending a message to the people who manage the profiles of our mutual relatives, to tell them about the reunion? I could do it for our mutual relatives - it could be a "test case" to see if it's worth spending the time on.
