All you have to do is scroll down to the very bottom of the page. Let's say you're in CSI: Music, and you want to see ALL the threads. Scroll down to the bottom of the page, and there should be a drop-down menu that says something like, Show: active in the Last week, Last two weeks, last moth, last year, all posts" or something like that. You choose the one you want, say "all posts" and then you hit the "change" button. There's your solution!
