At the top of every page, there is a useful set of breadcrumb navigation links, and I use it often. (eg "Physics Help and Math Help - Physics Forums > PF Community > Physics Forum Feedback & Announcements ....... Post New Thread" is the relevant linking structure I see as I write this post.) At the bottom of every thread page, though, there are only two navigation links, and neither seem particularly useful, considering how users are likely to navigate the site. They are "Previous Thread" and "Next Thread." Certainly, in my case at least, I do not scroll through threads in a forum one by one, in a linear fashion. Normally I'll just press the "back" button on my browswer to view the current forum index, but in cases where I view many pages of a thread in succession, the back button is cumbersome to use. However, the links at the bottom of the thread page are not useful either, so I have to scroll back to the top of the page (often this is quite a ways!) to use the breadcrumb links. I think it'd be a lot more convenient if we could just reproduce the breadcrumb links at the bottom of every thread page, immediately following the last post of a thread. This would provide users with instant access to most immediately relevant parts of the site that they would be likely to want to view upon finishing a long thread. I don't know if carrying out this suggestion would involve a hack that would be a nuisance in itself to implement, but if it's not too much trouble, I think this modification would make forum browsing easier and more convenient for everyone.
