Ivao.ORG is run by a scandalous Dictator who claims to own the "real" IVAO, the owner is responsible for many hackings and problems at ivao.aero, thus reducing himself to a little child. He was a bad man, and it was decided that it would be better for the organisation if he was "removed" from staff. He was offered a position as an honoury member, but sulked like a child and decided to cause problems..
IVAO.aero is the one you will want to register at and spend your time at, we have also just become an official NPO (Non Profit Organistation).
