Manual talk:UserOptions.php

Can this be used to change specific users options, or is it an all or nothing kind of thing?
I was wondering if i would be able to change specific users options with this or if it was all users or nothing?
 * userOptions.php allows you to change a user setting for all those users, who currently have a special value set. So: Yes, it is possible to only change one special value into another one. --88.130.90.34 15:18, 3 January 2014 (UTC)
