MGAP, short for "Motors, Guns and Politics" is an adjunct mailing list to the MML. This is the place where off-topic, particularly political and current events discussions, take place.
As of this writing (January, 2011), MGAP is wide open, and unfettered by an official list of rules, and has been since 2007. Respect for your fellow MGAPer is the watchword. This is a policy that works well, even in a contentious group like MGAP.
