Old system you could simply double-click the bears icon next to the forum title and it marked all threads in that forum as read. New system doesn't have that, but you CAN do it differently. 1) ENTER the forum you want to mark as "read" 2) Click the "Mark Forums Read" link. You'll get the option to mark ALL posts as read, or only those posts within that forum. Make you choice. If you click that link from the "forums" page... where it lists all the forums... you don't get the option. It simply marks ALL posts as read.
