in announcement forum you have everything from "hey, check out this picture I'm posting as a test!" to "hey, we're getting together a national hybridZ show in..."
So it becomes pretty broad. For example, I completely ignored the Motorsports forum, because I don't visit it often enough. There's a 6 page thread there about a norcal hybridz BBQ and sac raceway meet. I forgot about it because it got pushed down and off the main page, until Z-Dreamer reminded me. If you look at all other forums out there, they all have regional subforums, because it's convenient. It groups people by locality, making it easier to communicate. ie. we have 2 zya's on the board, did you know that? One's in norcal with a 383 sbc, and the other is with a turbo 240z on the east coast.
