mwgsr -- I know you're not asking for any advice, but since I've seen so many automotive-related forums come and go, I'm going to go out on a limb and give you my feedback.
I like the colors -- grays/whites/blacks are good for forums, and your design looks sharp and clean. The links section is a good idea too.
However, I think you're going to encounter some difficulties in attracting a sizable audience, considering how generally targeted your forums are. Five years ago, you might have been able to launch a general workshop-type site. Now, since the web is so heavily developed, there are plenty of excellent *separate* websites for the different types of skills you are featuring. Someone in need of woodworking help will probably find better assistance in a woodworking community, rather than in the woodworking section of a general workshop community (unless it's HUGE). This is the same reason why we have avoided make and model-specific forums here (Ford, Chevy, Mopar, etc.). Excellent websites already exist that cover these specific makes/models.
I see you've covered several different subjects. To my knowledge, there is still room for web development in automotive electronics, and a little bit of room left in welding -- but there is tough competition; in order to succeed, you would have to have superior skills/knowledge/determination/resources/funding/luck than the other websites already out there. Fiberglassing and fiberglass part fabrication is fairly open -- you could easily devote an entire forum to that.
I know that it might be more reasonable to think that the more ground your forum covers, the more people will be interested. Realistically though, these days -- the more targeted your forum is, the more valuable of a resource it becomes.
Either way, once you generate some posting volume, we'd be happy to help you out with a listing in the "General Forums" section of our Knowledge Base
