SIGs exist to serve specialized needs within the greater organization. Special Interest Groups (SIGs) and Professional Interest Committees (PICs) are a tool by which the local chapters can serve a diverse range of special interests, boosting chapter membership. The Lone Star Chapter (Dallas/Fort Worth) began hosting SIG meetings three years ago. Currently, with four active SIGs, we are hosting an additional 100 to 200 members per month. This is how we built our SIGs to promote membership in STC. In the spring of 1990, a group of disgruntled contractors began to meet formally to discuss dissatisfaction with insurance plans for independents available through the society. We had been meeting informally for many years, to discuss the job market, rates available, and generally to gossip. We call it networking. personal contact or the sudden ice storm we had that night attendance was down significantly. From that point, we have kept a mailing list updated from our sign-in sheets, and sent postcard reminders about each meeting.
