Recruiting New Members
The best way to recruit chapter members, and new members for ACM as well, is through personal contact. No quantity of mailings can be as effective as personal contact.
The first source of potential chapter members is ACM and ACM SIG members in your area. ACM headquarters can send a message via listserv to members in the appropriate area detailing your chapter's activities and mission.
Your professional associates are also potential members. Opportunities for professional growth and networking abound in local chapters of ACM, and many of your colleagues and associates would find the contacts and activities highly rewarding.
Many other sources of members surround you, and all should be explored. Companies using computers or dealing in technology services have personnel who are potential members. Local colleges and high schools have staff members interested in or active in computing.
