on my own (mediawiki) wiki a user has to be unsysoped for legal reasons, I am the Admin and have burocrat status.
The page "Spezial:Makesysop" just allows to create, not to set or to remove sysop-rights.
again: how to un-sysop s.o. within my user-base?
You can do that via direct access to database, look at table 'user', column 'user_rights'. You can do something like UPDATE user SET user_rights="" WHERE user_name="BadUser"
