Being one of the distributors over there, who moved over 13,000lbs. of green to a several hundred unique members, I will refrain from answering since I'm obviously biased. But I would really like to hear responses to the good, bad, or ugly. There are possibly some aspects about the Club which seen from the other end of the stick, would be good for me and the other distributors to hear about.
I know there are a handful of people who have memberships on that forum as well as this one, in fact, that's how I heard about coffeeforums.com.
The main reason I don't spout off more to promote GCBC is that buzzroaster (member here) is in the process of setting up his own greens-moving system.
