Anyone with an account may choose to be notified when a certain page changes using the 'watch' feature and 'my watchlist'. MediaWiki does not let people 'own' pages; however, the watchlist feature, along with the ability to revert changes, keeps interested users involved in particular pages without the drawbacks of giving someone absolute control over a page.
