Hi. You can make a user an Admin by going into their contributions (they're labeled when you reach their profile page) and click "User rights management". There, you see a tick box with "Admin" labelled on it; tick that, click "Save" and you're well on your way.

I'm assuming you're a Bureaucrat on said wiki? You have to be one of them to assign Admin rights. See Help:Admin for further details.
