The Illuminati Organization website allows people to request membership by submitting an email address and a first and last name. As of 2014, joining The Illuminati offers a membership certificate for $16.97.
Joining The Illuminati's terms and conditions state that it is not associated with any other organization, and it only guarantees to provide the membership certificate. Any invitation to physical meetings or activities is not promised.
The Illuminati is believed, by some, to be a secret religion that protects a great secret about human existence. It is widely debated as to whether or not the Illuminati exist or are just a myth.
