Here's an example. Look at the timestamp of my post #60 in this thread: https://www.physicsforums.com/showthread.php?t=663012&page=4 About an hour later, I got "update" email from PF notifying about this thread. But why? The timestamp on the email was about an hour after my most recent access of that thread. So why is PF emailing me? This sort of thing has been happening for ages, and it's a bit annoying. Can this be fixed?
