A: Membership is one of The Commonwealth Club’s most important sources of support, and the Club’s relationship with its members is of an utmost importance. The Commonwealth Club does not sell its membership list to other organizations. However, in order to assist in its membership and fundraising efforts, the Club periodically rents and/or exchanges the names and addresses of its members and former members with other organizations, using a process that does not permit the other organization to review or retain a copy of the membership list. Rental and/or exchange of the list allows the Club to expand its membership base by obtaining the names and addresses of other likely donors, and provides a valuable source of additional funding. Club members have the right not to have their names and addresses provided to other organizations. Members are given the opportunity to indicate this preference in making membership commitments by mail, phone or online. They may change their preference at any time by contacting the Club’s Membership Department by phone at (415) 597-6708 or by e-mail at membership@commonwealthclub.org to request a "no rental or exchange" designation.
