I'm looking for an ability to assign an "Approved" state to a wiki article, which then becomes the default page that one lands on when going to that article, and still permit edits to progress for future versions (which one day may become the approved version after a configuration control board accepts changes.)
This permits a known, agreed definition on an article (that the larger community sees), while allowing a work in progress to be performed against the article (which a small team works on). The larger community can still access the work in progress, if desired, and run a "differences" view, but defaults to the approved version.
