How you teach the rules of Go to beginners will depend on
Few Go clubs could survive without publicity. Every member of a club was once not a member, found about about the club somehow, and joined. If you want your club to survive, you will need to recruit new members.
Before starting a club, you should investigate what Go clubs there are near you: if you are in Britain, you can find them shown on the BGA club map. You might visit one of them, for ideas and assisitance. You might plan your meetings to be on different days from theirs, to avoid clashes and provide more choice for nearby players.
