I figured out how to figure out how many Matches with whom I have Sharing that I expect to lose.  If you sort your matches by: Click on Contact Status, the first category to display is Sharing Genomes Introduction Accepted View Conversation. IOW none of this first set of people have made themselves Sharing Genomes Public Matches View Conversation (approximately the next category).  And despite Jim B's sanguine belief that 23 thinks these people are all NOT ANONYMOUS to me at least, I have seen no indication anywhere that that is the case.  (It's my fault that I didn't ask that Jim B show me where he got the notion that these people are no longer Anonymous by 23's new definition.)  IOW if I'm correct and all these people out of my ~1000 matches, are deleted, I'll lose 30% of my matches including my top match besides my sis.  And she'll lose ~18% (and that same top match). And also I haven't seen their new email system, but all these nicely filed emails would be lost (the only part of their email system that used to be decent). It occurs to me that it's far worse than 30% if you count only % of 3rd or 4th projected cousins.  Hmm, it's ~60/150 = 40%. BTW in the column on 23 that discusses the change, the last entry by STAFF as of ~1/2 hr ago was Due to Technical Issues, the (whatever) has been delayed until 11/12. IMO I expect that the Technical Issue is: Whatever test run they ran determined that LOTS of Matches that SHOULDN'T be deleted WOULD be deleted by the program that the (probably) contract personnel had concocted to do the deleting.
