I use the 'mark forums read' button quite regularly, especially this time of the year when new comments come in so fast. My unread post page fills up quickly with all the newest posts and I would like a way of organizing it. I don't like marking all as read because I might miss something. Is there a way to mark a single thread as read on the unread page?

Not ideal, but what I do is click on the post link then immediately click the back button on my browser.
