I have recently posted a new topic. When looking at my topic I can see that the headline of my topic is displayed in gray, while most of all other topics are displayed in black. What’s the difference? Neither the number of views, nor the number of replies seem to make the difference.
In the above screenshot you can see that this topic title is shaded grey, indicating I have read to the end. While the one below is white, indicating I have not read to the end of it.
