I don't know about you but when I'm reading posts and get to the bottom, I want a quick way to go back up and click New Posts. You might suggest that I use the two finger swipe to go back to the list of threads... or that I press cmd+up but in doing so it doesn't mark the thread as read. The other alternative is that I scroll back up to the top... that is time-consuming. It's late but what I'm trying to get at is that it would be useful when browsing the forums to have a link that would take you to the top of the page. If you have been on various websites before, you might have run across this or in other forums.
