I'd recommend posting all events to a calendar somewhere... as the information on goings on is not consistent, nor is there a consistent place to view the announced events. It needs to be in once place, and ideally allow for folks to subscribe to a calendar. CCCKC has a google calendar sidebar that list all of the dates for events right on the front page (
http://blog.cowtowncomputercongress.org/). This allows anyone to easily see what is going on in the space.
I would also highly recommend adding a vision statement to the main tcmaker.org site, and regular official meeting dates, etc, rather then having them somewhere scattered in the forums.
Also I would recommend having scheduled content, pick someone to present on some topic, or run a small workshop each month, announce to the world that this is happening, these are very important keys to drawing a larger crowd. Maybe get William Gurstelle (Minnesota native) in to speak or give a demo, or invite other famous makers to the shop (Mitch Altman, etc) to run a demo or something to get people engaged, and most importantly interested in the maker scene.
Sorry to rant, but I do want to see this succeed and these are some lessons that I've learned help to draw a larger crowd (I've been running DC612
http://dc612.org) for almost 3+ years now. Anytime we have content that is somewhat structured, more people come to play.
