My guild has about 250 members. The guild has 2 chapters, a morning & a night. Executive board consists of a president, vice-pres, secy, & treas. Also a day co-ordinator, day secy, day treas and a night co-ordinator, night secy & night treas. Each chapter plans its own program, but a few times a year the "guild" sponsors the program & workshop with nationally known quilters. Challenges & holiday mystery are " guild" activities, but each chapter plans its own block of the month, small workshops, etc. Hope that info helps you.
