Mark All Read

I think each forum needs a "Mark All as Read" button. It's cool to see new posts better indicated this year, and with that functionality added, I want to use it the way I do in any other forum to mark what I've read and what I haven't. Short of a way to quickly "catch up" threads I'm not actively involved in, it's harder to tell what's strictly new. Thanks, and the forum updates are looking good this year.
