Every Meetup.com group should have an ideapals.org group, adding everything from linked-in, base-camp, and collaboration built around ideas: even a chance to win a $50,000 website and marketing campaign: and it is all free: I would like to invite you, and your members, to participate for free in the first social network every built around ideas instead of pages and posts: http://ideapals.org; anything you do here pays you in NODs (natural overtures of distinction) and you could win a $50,000 prize one of two ways: be one of the first 5000 to sign up and be lucky (there are over 1000 members already only 30 days after launching the beta); or be the most active participant (the most nods).
I would also like to introduce you all to my famous mentor: Israel Rothman, who builds niche social networks to target a marketplace.
