Maintaining contact

Support groups maintain interpersonal contact among their members in a variety of ways. Traditionally, groups meet in person in sizes that allow conversational interaction. Support groups also maintain contact through printed newsletters, telephone chains, internet forums, and mailing lists. Some support groups are exclusively online (see below).

Membership in some support groups is formally controlled, with admission requirements and membership fees. Other groups are "open" and allow anyone to attend an advertised meeting, for example, or to participate in an online forum.
