the ***ONLY*** value that facebook offers the TMA is to redirect folks to the TMA website.
if they don't register at the TMA website, then they are never participating and their "read only" numbers are meaningless to a fair degree.
there have been 49 new forum registrations since the beginning of march 2020. 3 have become contributing members. 15 have posted and 34 have yet to make a post.
so, i see no reason to believe that the demise of the active TMA facebook page has caused any lessening of TMA forum posting. we still have a TMA facebook page as read-only, and who knows where those 49 registrants originated? i will be adding a new mandatory field to the registration, asking how you found out about the TMA.
