Too complicated? Compared to what?

This is probably one of the least complicated sites I have ever seen. Certainly the least complicated one I have created.....
Actually I thought I was being EXTREMELY conservative with the number of forums here. I could have easily put in 10 times the number you see now with very little effort. And honestly, that may happen in a few years if traffic warrants it.
I look at the purpose of a forum being not only having members POST in relevant forums, but also being able to FIND info they may be seeking as easily as possible. As the number of posts increase, the relative number per topic will increase as well, which then leads to subtopics. Just the
Maintenance, Mods, & Tips forum itself, if traffic warranted it, could be broken down into separate forums for each of the main topics there. Heck there are websites dedicated to DETAILING all by itself.
There are always tradeoffs for something like this, of course. A larger format with a lot of forums may actually be better for more accurately categorizing topics, but it can be confusing, since overlap is inevitable, and even if traffic is rather heavy, the number of posts spread out over a large number of forums just makes it LOOK much more lightly traveled than it really is. Which will sometimes put off prospective new members. But on the other hand, having a single forum as a catchall for ALL postings, although looking very active, makes trying to find anything a real chore. So you simply try to strike a compromise somewhere in the middle, then adjust things as conditions dictate a change.
But honestly, trying to please everyone, simply because the breadth of experience will vary from complete wet behind the ears newbies, to people who have been visiting sites like this for years (even running some of their own), is pretty much impossible to do.
