For some reason when I visited just now it’s showing that I have unread posts going right back to october 23rd, despite the fact that I only visited this morning. Also, the image in the top-left of the forums ain’t working.
It’s not affecting my ability to use the forums, just thought I’d note it in case it’s a symptom of a wider cock-up.
It looks like you now have to visit the thread for it to be considered “read”, instead of having to have visited the forum, which is how it appears to have worked previously. It caught me by surprise to. Personally I don’t mind it, but I do click the “Mark Forums Read” after I am finished to prevent the confusion.
