Well, today I went to my user Cp and "readjusted" everything. I am now getting email notifications from one thread; the others I've subscribed to just may not have any new posts.
I do notice, however, that I am getting DOUBLE notifications: the same notification sent twice . Oh well, at least I'm getting something. Thanks, Tech Board Mods!!
Good luck to the rest of you who are still having a hard time with the notifications !
