It was founded in 1988 by its General-President, Ruud Janssen. Chief Executive Officer is Daniel C. Boyer. Treasurer is Keith Bates (UK) since 1990, and mail-artist Dobrica Kamperelic (YU) is the Legal advisor of the IUOMA.
Anyone can become an officer of IUOMA just by asking for a position, provided no one else has already occupied it. Accordingly, the group has a "Grand Master", an "Ambassador to Cyberspace", and so forth, and none of these positions have any meaning. This is similar to, for example, Dogbert's New Ruling Class - a loose mailing list/fan club run by Scott Adams.
