I only noticed them now so I don't know if they had always been there, but what do these icons mean?
Also, is it a new thing, those blue colors that indicate activity when you're viewing the forums in the main forum view? Or did I just notice now Anyway, I like it a lot
When you post, either a new thread or answering in, you can add icons to the header of your post. You will find these icons at the bottom of the editing form in advanced mode.
The icon have no specific meaning...
This function has always been here for what I remember...
