The Official TWiT Wiki:Admin Report
To ease moderation, mediawiki provides a "patrolling" functionality. Basically, the admins can assert that certain edits are "patrolled" and therefore not worth investigating. Unfortunately by default, the only users allowed to patrol edits are sysops. If you add a new group, let's say "Trusted" users, then those users will be able to edit the wiki and have their edits auto-marked as patrolled. This is called the "autopatrol" permission. If you want, you can also grant the "patrol" permission to Trusted users, allowing them to mark others' edits as patrolled. Once we have the majority of edits patrolled, we can do simple filtering on recent edits to investigate only unpatrolled edits and hunt for spam that way. What do you think?
To effect this change, you'd have to do this in LocalSettings.php:
$wgGroupPermissions['Trusted'] = $wgGroupPermissions['user']; $wgGroupPermissions['Trusted']['patrol'] = true; $wgGroupPermissions['Trusted']['autopatrol'] = true; /* optional */
