Well, as far as forums go, the old one was even a little bit off from the "standard". But this new one is just something from a whole different planet. I've been a member of many forums for at least 10 or more years now, and this is by far the weirdest thing I've ever seen. I can see how the web designers are trying to emulate facebook. Only problem is this is not a social network or blog site. It's a place to talk about a very specific subject matter.
Here are my favorite forums and you'll notice they are all a very standard layout and operate much the same way:
honda-tech.com
tl.acurazine.com/forums/forumdisplay.php?f=93
tamiyaclub.com/forum/
I can tell they are working on making it a bit more conventional and there still a bit to be done. Until then, this forum is going to be painful for those of us that frequent many sites on the internet and not just this one.
