I've waited quite a while, but these forums really need to be fixed. In a day and age when many tiny websites have forums that work on a wide range of browsers (the forum templates are available for free) it is unacceptable for a professional company to have forums which are this bad.
Specifically, the forums more or less dont work on Firefox or Opera on two different operating systems (KDE linux and WinXP). Opera wont post posts correctly, and wont let me view threads that I have responded to even if I do fiddle around enough to get a response in. Firefox also doesnt post correctly, wont let me view threads that I have replied in, and creates 2-5 pages under the back button for every single thread (should be 1 page per thread obviously), making backing out of a thread strange. It also appears that all posters have the problem that their posts dont go up right away, leading to lots of self bumps. While I understand that there are reasons for this, pretty much every other forum out there allows for immediate viewing of posts.
There is nothing worse for the confidence of prospective customers or even current customers than having a website that looks nice, but turns out the be rather amateury at best. It reflects quite poorly on your company, and I would view it as a high priority.
