Eligibility for membership in the corporation and the rights, privileges, and designation of classes of members are as provided in the constitution and bylaws of the corporation. However, an individual who did not serve honorably in the Armed Forces of the United States during the period beginning April 6, 1917, and ending November 11, 1918, is not eligible for all classes of membership.

Each member of the corporation (except an associate or honorary member) has one vote on each matter submitted to a vote at a meeting of the members of the corporation except the national convention.
