I see. Can be confusing since this is a universal section I guess. You can try PM'ing Jason
and suggesting it to him. Not sure if he manages the available sections, but I'm sure he can take the feedback.
As for the redirecting, that happens when you just go to the domain name. All the domains redirect to the bimmerpost.com parent site. You have to add "/forums/" to the end to stay on the forum for that particular site.
