I agree with StubbleJumper, and voted to keep the current format. It will take a little time to know how and where the discussions go, but what you have is a great start. If we find certain sections are unused, you can always fold them into another relevant section, or put everything into the general discussion heading. I think in time the activity of the board will reveal if we need more or less subforums, but the current structure seems right to me for now.
FWIW
