Extension:PageNotice

The PageNotice extension provides a way to define fixed notice messages for the top or the bottom of each page, or entire namespaces. Such fixed messages are defined by creating MediaWiki messages following a special naming pattern:
 * top notice for page XXX: MediaWiki:top-notice-XXX
 * bottom notice for page XXX: MediaWiki:bottom-notice-XXX
 * top notice for pages in namespace NNN: MediaWiki:top-notice-ns-NNN (where NNN is the numeric namespace ID)
 * bottom notice for pages in namespace NNN: MediaWiki:bottom-notice-ns-NNN (where NNN is the numeric namespace ID)
