Boonex can best make a difference by swallowing its pride and not trying to reinvent the idea of starting a green community. Use your product - community software - to support pre-existing Green Communities and Green Businesses exactly how Zaadz is used by Whole Foods and Gaiam to power http://www.gaia.com/. I've checked, and the following sites look like they would benefit from your software and are not so established that they could not make a change: http://www.2people.org/, http://www.greenbusiness.net/, see more http://outforaride.com/, and http://www.veggiecommunity.org/. http://www.fixingtheplanet.com/ is built around their forums, but if you offered to help them migrate, they might bite. I don't know how involved you'd like to become in politics, but if the software works then it would be a great platform to build grassroots communities around, like Greenpeace and Green Parties.
