After more than a month of not receiving, via E-Mail, notifications from the OGR Forum https://ogrforum.com/...2#176413147189832542, my notifications have been restored.
Alan Arnold responded to the topic in the link above saying that I was the only forum member that had reported such a problem. Alan did get help from those familiar with the technical operation of the OGR Forum, including Rich Melvin. Rich, after much investigation, did look into my user account and noticed that, somewhere, deep in a "Settings" menu, the option to suspend E-Mail notifications had been clicked and activated. Rich told me to deactivate that setting and all would probably be well. I deactivated the option to no avail. This transpired in early July. I was still without E-Mail notification service. I could still view the forum to make posts, etc.
About 3 days ago, miraculously, my E-Mail notifications reappeared. Though, being computer and somewhat internet savvy, I know that magic does not happen. But now, The E-Mail notification service has come back with a "vengeance". Where before, I was only getting notifications on forum topics to which I either liked or replied, it seems now that I am being notified, via a bombardment of E-Mails, of topics of which I have never heard. Whereas before, I was receiving about 50 to 60 notifications a day from the OGR Forum, I now receive 200 to 250. Can anyone now suggest an adjustment to my account settings to get this back to what I perceive to be normal E-Mail volume?
Still, even with an exploding E-Mail mailbox...
