I've searched mediawiki endlessly, but I can't seem to find an answer as to how to Selectively add html/wikitext to the top of articles while they are being displayed to the user.
So if I had a Namespace:, I want every page within the namespace to have a piece of html tagged to the top of the page while it is being display to a user.
Could anyone clue me in to a hook or way to do this? - Hunter F.
