Most A.A. members meet in A.A. groups as defined by the long form of our Third Tradition. However, some A.A. members hold A.A. meetings that differ from the common understanding of a group. These members simply gather at a set time and place for a meeting, perhaps for convenience or other special situations. The main difference between meetings and groups is that A.A. groups generally continue to exist outside the prescribed meeting hours, ready to provide Twelfth Step help when needed. A.A. groups are encouraged to get listed with G.S.O., as well as with their local offices — area, district, intergroup or central office. A.A. meetings can be listed in local meeting lists.
