The easiest solution (and probably also the best for SEO purposes) is to put your forum on a subdomain, i.e. forum.example.com
If you want everything on the same server it really depends on the rest of your site. Are these real files that you want to serve? Are these files generated by a CMS? Etc.
Thanks @pichalite it works great. @ARC also a good idea.. I will remember that for future addons..
I replaced your fadein animation with one from animate.css (FadeInBottom) which slides the rows up and fades in at the same time which looks great when scrolling normally but looks a bit crazy when you page jump (since they all slide up at the same time causing the scrollbar to go a bit crazy 🙂 ) so i set it back to the one you added. I will experiment with it to see if the users like it or not.. Thanks for your help.
