It's not a matter of trying to fill up people, but to fulfill people. Study circles hold great promise for both personal and social transformation, and several organizations are working enthusiastically to help people engage in them. This organization is a veritable gold mine of information on study circles. They also have an extensive annotated bibliography on study circles, a clearinghouse list of study circle material developed by a variety of organizations, training materials for study circle organizers and facilitators, and a newsletter - Focus On Study Circles . It has strong links with European folk educators, a valuable newsletter, exciting conferences, and enthusiastic members.
Forums range from small study circles to large town meetings.
Call them for more information. They'll also send you information on getting started, and four issues of a newsletter.
