What exactly is RC Patrolling?
It is a mechanism to check for vandalism. See RC patrolling
In MediaWiki 1.4 and above, a feature exists allowing specific users to mark items in recent changes as having been "patrolled" or "approved". This is useful when reviewing recent changes for undesirable edits, link spam and vandalism.
Marking edits as patrolled 
- To mark an edit as patrolled
- Access Special:Recentchanges
- Changes which are not patrolled will be indicated with a red exclamation mark
- Click the (diff) link next to an edit
- To mark the edit as patrolled, click the mark as patrolled link
Default ? 
Is it correct, that the default-value is true? --Nyks 12:11, 27 September 2007 (UTC)
- Unfortunately yes. I personally find RC patrolling to be very annoying, but it's set to true by default in DefaultSettings.php. --Sayuri 12:18, 27 September 2007 (UTC)
MK WIKI 
Hello. I need your help. We, on the Macedonian Wikipedia, have decided to implement the patrolling and bureaucrats, admins and autopatrollers are allowed to do this. We have voted and need to enable this option. So how to do this? I know that we need to add some codes to our MediaWiki, but I do not know which one and where to add it. The final step is to ask bugzilla to enable this feature. Can you tell me which code to add and to which MediaWiki in order to be this option available and also, I assume, that an article after installing this would have one patrolled version and one version for working on. Thanks--MacedonianBoy 17:53, 18 April 2010 (UTC)
