Having the "dealership/ordering/financing" subforum under the "discussion" forum seems counter-intuitive. Being the ONLY subforum in that section, it kinda gets lost. I know I've opened a couple of threads in "discussion" only to have them moved to "dealership/ordering/financing". I think it's because that subforum is so easy not to notice and I'm not expecting to see it there. I'm not even sure if any of the other main forums have any sub-forums within them. I think it would make more sense to move it to the main page. A minor nit though.

In our current beta forum, sub-forums have also been made to show up in the forum home. This should alleviate your problem as well as the problem of the sub-forums not being viewed as much:
