mark all threads as read

I'm sure you guys have had this suggested before, but it's really the only suggestion I have because it's the only real complaint I have. I'm more of a lurker than a poster and I have to say that not being able to mark threads as read without having to actually open every one of them has kept me a lurker. That and I don't have a lot of great things to say, but still ;-)

I have to admit, this is a functionality I really miss here. I'm so used to it on the other forums I frequent that I keep looking for it. (On the plus side - being able to flip between flat & nested is just so wonderful.)
