There is no Green Chip on RGE.
There are the Open Forums or free pages which are hosted and moderated by Parker. If you have not created a profile there, or if you are not approved for exempt status from moderation, your posts will not appear until they have been reviewed.
There is Don's Domain which is hosted by Don Schlesinger with several highly reputable blackjack authorities known as The Masters available to help answer questions and provide insight on blackjack theory. There are now several forums on the domain. This board requires similar subscription dues like BJ21 Greenchip does. A contest is now being held on this board in which blackjack questions are being asked. The person emailing in the most correct answer gets his choice of blackjack publication or subscription service for a prize. Be forewarned that Don expects posters to be grammar concious to maintain a more dignified site.
There is also the Pro Network which used to be known as Greenbelt. This board has heavier dues, and stringent security requirements. It is not easy to join this board.
