This just cropped up after the 12 hour outage yesterday. When I first do a "Science Forum Forum Inde"x, it shows all the fora with unread posts. But as soon as I read any post, when I go back ( or do index again) it shows no unread posts, and if I look at a forum that I know had showed unread posts, all the threads show as having no unread posts.
This really makes it hard to keep track of the current state of conversations.
