Members of the Corporation are divided into two categories: "Corporate Members" and "Members". Corporate Members are those donors in the top 75th percentile, based on accumulated donations and who have a vested interest in the organization. Corporate members are allowed to participate in nominations and elections, present and organize events (with Corporate endorsements), participate on special committees, represent the Corporation at certain events (with Presidential endorsements) and authorize/sponsor the participation of any otherwise unqualified individual in any Corporate program. Members are the participants, in general, of the organization's programs. Members do not have voting or sponsoring power, but are recognized as regular participants in programs and are entitled to preferential access to such programs.
