Someone asked so what's not to like about losing all the ANONYMOUS Matches.  Well: There have been multiple times when I got a match with someone and NO ONE with whom I was Sharing matched that person.  So I went to COuntries of Ancestry and Lo and Behold, both of us had 1 or more Anonymous matches with grandparent profiles LIKE (Vanuatu, Israel, Latvia, Slovakia). Now for those of you not getting it, how likely is that 2 person were to have that profile?  So I reported the good news to that person that yes our match was corroborated even though I had no idea with whom. Under the new system, those persons are just going to have to be uncorroborated and maybe that person will stop Sharing.  And if Jim B is correct that persons might be Anonymous to everyone but those with whom they Share, that person might totally drop off my list and I'll NEVER be able to write to him on 23 again.
