It sounds like there are two issues you are trying to solve here. 1) giving all rights to another user. 2) Stopping email notifications. I am guessing the latter can be done in your account preferences. I don't get any emails from Wikia. As for the former, can't you just promote them to Bureaucrat or Co-Founder status?
