Novice users like to write http://mywiki.com/wiki/My_article instead of [[my article]]. Provide a global variable, $wgForbiddenExternalLinks, that prevents this from working.

// Array of regexps
$wgForbiddenExternalLinks = array();
$wgForbiddenExternalLinks[] = "http://mywiki.com/wiki/.*"

When a user writes http://mywiki.com/wiki/My_article or [http://mywiki.com/wiki/My_article foo], the link itself is not rendered. A system message Mediawiki:forbiddenexternalinks is displayed, defaulting to "Don't use external links to yourself; use internal link syntax, [[article name]]."
