What does an exclamation point next to a post mean? Notice it on one of my post

 

You mean like this post has! It's added by the user.

 

exactly. I don't recall adding it. I simply updated my existing post

 

I'm not sure how it would get there without your input unless you post was edited by a staff manner. Which would be indicated at the bottom of your post. That would be a very unusual edit though.

You can edit your post to remove it if you like.

 

Thanks. Will do
