I used to receive prompt notifcations via email of PMs and resplies in threads to which I had contributed. Since the return, they're coming more slowly, if at all. I haven't analyzed them, but it would appear that the notification emails either aren't being generated simultaneously with the PM or post, or they are being held in a queue, and signing on before they are sent cancels them. But that's only a hypothesis.
Is anyone else not receiving email notifications as they were four weeks ago?
