I have commented on a couple of posts and answered a direct message, everything still registers as unread. I have the same number of unread things in my inbox now that I did when I started. I am not sure if there is a glitch on the site or in my laptop. I have stuff to do so will try to check back later.
If I ask not to follow something that I had commented on, is there a reason that I still get updates every time someone else comments? That's another reason my inbox is filling up constantly.
