Site Research

I need a full listing of sites where freelancers, consultants, and work from home people are members of. These are not sites like peopleperhour, guru, elance, etc., where freelancers find jobs, but sites that have forums, where they are part of a community of fellow freelancers/consultants/work from home people.

We offer a complementary service for helping these people with their sales and marketing side of freelance life, and want to begin posting to attract more members, so need a full list of sites (beginning with the US and UK, any other countries welcome as well).
