It would be extremely nice if the site had navigation "crumbs" at the bottom of the page. I think it's just a browsing comfort instead of having to scroll to the top or hitting a back button. A lot of other vBulletin based forums use them and it's just something I've learned to enjoy. If it's something you feel would add to the site, I could also send you the coding if it helps.
Here's an example: home -> category -> subcategory -> pagename
Thanks,
Corey
