I've just split these few posts out of your main topic - might come in handy for someone else one day
Oh, and I don't recall any method of preventing/enabling users receiving post notifications, other than to make it invisible, but that won't stop prior requests for notifications. You would have to directly edit the cms_bbtopics_watch table for specific/all users.
(also removed your question in the last post of the other topic)

This is really weird. I wasn't receiving notifications in this (original) thread (even though I started it). Then I received one for your second to last post, but I didn't get one for your last post. I've had no other issues with email lately so I don't think its my mail server. I'm subscribed to many threads on many other sites and have had no problems getting notified by them.
