The following roles are defined for tournament purposes:
- Tournament Organizer (or TO)
- Head Judge
- Judge/Tournament Admin
- Lead Admin
The first four roles above are considered tournament officials. The Head Judge and judges/tournament admins are collectively considered judges. A single individual may act in any combination of tournament official roles. Individuals who are not judges at a tournament are spectators in any match in which they are not playing. Members of the press are also considered spectators.
