I'm not sure if there's one built into the forum software, but if there is can it please be enabled?

I know it's just laziness on my part, but if you're reading an exceptionally long thread and you get to the bottom of the page, there's no link to go back to the forum so you're forced to scroll up to the top of the page again. A 'top' button at each post or even a forum link at the top and bottom of each page would help.

If it's something that's gotta be coded especially, don't worry about it, I'll just keep doing what I'm doing.
