Thanks for the question.
As you can see, here at the forums we have several different ranks. Hylian Knights, Hylian Nobles, Moderators and Administrators.
To become a Hylian Knight, you must show outstanding posts as well as a friendly, relatable and respectable personality. Hylian Knights serve as role models for the community.
Hylian Nobles are long term forum members, normally retired moderators who have provided years of service. This rank is incredibly difficult to obtain and is reserved for a select few.
Moderators serve as the forum's police force. They enforce the rules, seen
here and maintain order. They move and delete threads as well as dealing out infractions, warnings and sometimes bans. There are no select requirements for becoming a moderator, as the issue is normally dealt with via voting. However, moderators or rather, those who wish to be moderators must show exceptional understanding of the rules as well as knowing how to control and deal with situations. Good grammar and forum presence are good grounds to begin on.
Administrators are the ones who run the forums. This rank is not like the others. Coding knowledge as well as all of the above qualities would be needed in order to become one.
I hope this cleared things up for you a little. I didn't go in depth on everything, but this is the basic know-how on how things work around here rank wise.
