Check your junk/spam folder. Virtually everything I get from this site goes in there, and I haven't been able to stop it, especially after cleaning out trackers, which Outlook (and probably others) use to know who is okay.
Not a bad sugestion but I get every other notification, just like the one I got about this. I must of not checked the box when I made the post to receive them. Now that I've responded to my own thread, I am getting them.
