I have found numerous threads, some of which I originated, where I have subscribed and specified Instant Email Notification, but do not receive any email notifications of new postings. Some work; some don't. Obviously, my profile includes my correct email address or else I would not receive 'some' notifications. It's just inconsistent. Sometimes I will receive an email notice, and I go to review the thread, and there were already two or three postings several days prior to when I received notice. What's up with that?
