ArmchairGM aims to be the ultimate community of sports fans -- a place where fans of games ranging from baseball and football to auto racing and mixed martial arts can congregate around a common theme: Fans rule. ArmchairGM uses MediaWiki -- the same software as Wikipedia -- because ArmchairGM believes in open doors. Any fan should be able to participate, and at ArmchairGM, any and all sports fans are welcome to join the community.
