How come I don't always receive email notifications for new posts? I've verified that email notifications are turned on. I do receive a lot of notifications so I don't think it's an issue with my email account. I notice it happens often on threads with a lot of people posting rapidly. My only guess is when I'm notified about a new post and then I read the entire thread after the new post I was notified about - the system "knows" that I'm caught up so I won't receive notifications on those other newer posts? Or is it something else I should adjust?
