Others may have disabled this function, as I have. It simply does not work well. At all. I often get email notifications several hours, or even the next day, after a reply has been made to a thread to which I am subscribed. I often get such a notification of a reply that was before my reply, many hours after I reply, leading me to believe that someone else may have replied to my reply, when there haven't been any replies after mine. It is not my email. It is the notification function of this web forum. It would be nice if someone fixed it, then those of us tired of this could turn back on the notification function. Plus, when I have it enabled, I often get several email notifications of the very same thread reply.
