I'm a member of 2. One is Joy of Connecting (national group for women) and that one has brought me the most clientèle. Mostly because I can go to any meeting I want in any city.. so it's very versatile. It's only $25 each visit.
The other one is a local group, and I can only go to that once a week and in the city I live in. It's a bit limited, but I've grown to adore the members of the group.
My goal is to join the Chamber of Commerce and WORK IT!
