You can use Special:UserRights on your wiki to change the user rights of a certain user. You can also use the link in Special:Contributions that says "User rights management" (on your wiki). I think those are the two main ways to promote/demote someone. Do make sure that admins (and especially bureaucrats) should be people who have done constructive work on the wiki and should be trusted in the entire community.
