// ****** USERS WITH QUERY RUNNING PERMISSIONS ******
// The users specified here will be allowed to run queries from the control panel.
// See the above entries for more information on the format.
// Please note that the ability to run queries is quite powerful. You may wish
// to remove all user IDs from this list for security reasons.
$config['Admin']['canrunqueries'] = '';

// ****** UNDELETABLE / UNALTERABLE USERS ******
// The users specified here will not be deletable or alterable from the control panel by any users.
// To specify more than one user, separate userids with commas.
$config['Admin']['undeletableusers'] = '';

// ****** SUPER ADMINISTRATORS ******
// The users specified below will have permission to access the administrator permissions
// page, which controls the permissions of other administrators
$config['Admin']['superadministrators'] = '1';
