Be very careful when you do this:
 * 1) Go to Special:UserRights on your wiki.
 * 2) Enter the username of the user you want to promote and click Edit user groups.
 * 3) Click the "administrator" checkbox (you might want to click "rollback" too, but it might not be necessary).
 * 4) Enter a good reason for the promotion and click Save user groups

If you want to check that the promotion went through, go to Special:ListUsers/sysop on your wiki. The wiki engine calls admins "sysop" internally.
