Apologies if this has been discussed before.
When l open a topic for the first time and then go back to the overview page, the number of unread posts of that topic will be shown. Is there a good reason for that? l find it annoying. Makes me go back to that topic and scroll all the way down to make that post count disappear.
Doesn’t bother me at all. OCD? 
I find it helpful, lets me know when a topic I have been reading has new post or if something has happened and the. numbers explode.
I think it’s a bug, but it doesn’t stick around - you don’t need to go back in and “read” all the posts, just visit a different thread and that buggy count will disappear.
Or maybe it’s a feature letting you know that you didn’t finish that thread. 
The important thing is that you can disregard it and it goes away by itself very quickly.
Too many little numbers on my screens. Some pesky ones for Wordpress plugins for example.
Nice, ask a question, and you’ll learn something.
You can adjust this on your Preferences/Forums page. Don’t set forums to Watching or Tracking and you won’t see that.
Nah, that’s not it. I mean the number that shows up when you visit a topic in a forum you are not watching or tracking and then go back to the homepage.
But like @Ender says, the number goes away when you switch to another topic. So all cool.
For me it’s like someone telling me: “Hey you haven’t finished what’s on your plate, buddy!” “You DON’T LEAVE THE TABLE UNTIL YOU FINISHED WHAT’S ON YOUR PLATE!!!” [crank up the volume and insert the voice of my father…] I am damaged, what can you do… 
These numbers in the blue circles? What I said should work in that case.
Yes. Those numbers. But they appear for all topics, watched/tracked or not. For example I am not watching Greater Formosa, I open the thread and look at the first post, then click on the site logo to go back to the homepage, and the number shows up.
I guess the idea is to let you know that you just left that thread and you haven’t finished reading all the posts in there?
I have the same thing. Returning to the forums often has topics that say unread that I’ve posted in and the unread part is my own post.
Discobot wants you to double-check before posting? 
Hmm, you’re not watching that topic either, so I’m not sure what’s happening. I’ll look into it. I think it must be a bug.
