Hey Brion, Thanks. It does look like the code that adds the category links takes place in Parser::replaceInternalLinks, which appears to be only called if Parser::parse is invoked on the article being saved. We are actually using a Special page to create request articles, so visitors can come and submit a request for how-to article to be written about, so the newly created articles are not necessarily parsed automatically. It's a slightly different approach we've been using to reduce the amount of wiki-knowledge that's required to participate in our community. http://wiki.ehow.com/Special:RequestTopic So it looks like the hack-workaround for this is to parse the article after inserting it into the database, that seems to do the trick for now. $article = new Article($title); $ret = $article->insertNewArticle($details, "", false, false, false, $user); $options = ParserOptions::newFromUser( $wgUser ); $wgParser->parse($details, $title, $options); Thanks!
