I'm not in the Sustainable Wall solar group either. Just thought I'd let you know it exists and is active on this site. Our other most active groups are community kitchens, gardens, bikes, chickens. You might want to take a look at our 2010 annual report to get an idea of the range of things we do. Also note we're on Twitter and FB which some busy folks like you prefer to follow.
You know we have a very active Wallingford Solar group?
We're meeting this week with SPU and City Light to discuss community supported solar atop the North Transfer station that is being remodeled at 34th and Densmore. Let me know if you are interested and want more info about this sort of community project.
