If you are a bureaucrat and administrator, you can go to the page that looks like http://yourwiki.wikia.com/wiki/Special:UserRights

You can type their username into the text area, after doing so, if you typed their name correctly, it will pull up a menu for the user rights that you can give them. Select admin, give a reason for why you're giving them admin, and hit the "ok" button.
