Have you ever though of making the forums more general, i.e. topics like Zaurus hardware questions, zaurus applications? I think that you would get a lot more people involved if you had more general topics vers the groups broken down by state. Don't get me wrong I think the site is great, easy on the eyes to use and well organized. Keep up the good work!!
I've setup the forums to mirror each regional ZUG that's been created, that way people within that ZUG can have discussions of their own.
I've been also thinking that this site could be a resouce for Zaurus users, not just developers. I like your idea of creating more forums for general Zaurus discussions. My only concern is that we don't duplicate what's being done elsewhere (ie. zaurus.com/dev/board).
Let me create a few more forums to accomodate your request... please let us know if you like it or not!
