Close but no cookie, Tom.
CGN is
CalGuns.net. A very popular CA gun board (perhaps the largest such board in CA). This is not to be confused with CGF,
CalGuns Foundation, of which Gene Hoffman is (at the very least) a Board member (and founder).
While CGN and CGF are not related, most members of the CGF Board are members of the CGN gun board. A lot of what the CalGuns Foundation does, can be seen and commented upon at CalGuns.net.
CGF supports CA gun rights through litigation, education, and outreach initiatives.
