You mentioned that you wanted coffeed to be fairly limited member's-numbers-wise. I'm wondering that if this is true, and the forum won't be crawling with hundreds of members, maybe there are too many sections.
Not that it's any sort of model at all
, but the reason we have just one section on the BGA board (and for that matter, the Roasters Guild board) is to limit the number of mouse clicks you have to make to get to the content.
Just my feedback... the sections could be consolidated down to just the main categories of: coffee, grinding, machine, and barista... with a brief summary of the sorts of topics to be contained within. My clicking finger hurts when I come to coffeed.
