Help:Extension:FlaggedRevs

is an extension to the MediaWiki software that allows a wiki to monitor the changes that are made to pages, and to more carefully control the content that is displayed to the wiki's readers. When FlaggedRevs is enabled on a page, each subsequent version of the page can be 'flagged' by certain editors, to indicate that it has been reviewed and found to meet whatever criteria the wiki requires. A wiki can use a scale of such flags, with only certain users allowed to set each flag.

The ability to flag revisions makes it easier to co-ordinate the process of maintaining a wiki, since it is much clearer which edits are new (and potentially undesirable) and which have been 'accepted' as constructive. In addition, however, it is possible to configure pages so that only revisions that are flagged to a certain level are visible when the page is viewed by readers; hence changes made by users who cannot flag the resulting version to a high enough level remain in a 'draft' form until the revision is flagged by another user who can set a higher flag.

FlaggedRevs is extremely flexible and can be used in a wide range of configurations; it can be discrete enough to be almost unnoticeable, or it can be used to very tightly control a wiki's activity.
