Settings are good. I wouldn't sweat it, Jon. It's probably just a matter of me not fully understanding what triggers an email notification. I'll get used to it. Great work. You could stop and this point and I, for one, would be perfectly happy.
There is no email, at the top there should be an alert advising you of this thread and now that I'm quoting you there should be another alert.
Yes (and I did get an alert from your post), but in my mind I should be getting emails when there's a post to a subscribed thread and I specifically asked for immediate emails. It seems to me that there were posts added to subscribed threads that I was not notified of (again, even though I checked the "immediate email notification" box). I can't swear to this and I'm not overly concerned about it, either. Pretty sure it's just pilot error one way or another.
