There is no solid requirements, I would guess you would have to have extensive knowledge on clans and orgs as well as the rhetoric to effectively communicate and debate your ideas and thoughts. You should start with applying for clan council if this is the route you would like to go down. They are currently undergoing a mass recruitment. Although this position comes with no publicity as it remains a secret who is on the council.

Different question entirely, unsure why you linked to this as no one actually answered his question.
