Rather than to become a site with too many forums - I believe that the forum in question was segmented out to the various Tech forums 5 or so years back.
We now have Wings-Wheels and Keels as a catch-all forum for non-GT40 subjects. I think the only way Ron would want to add any more forums would be if they were sponsored vendor forums.
That way I can search the whole site very easily. I am not sure how many people know how to use google search this way. It may be worth changing the search or adding a sticky comment at the top of the forums.
