Hi, We are developing a project of an online encyclopedia of simple technologies and practical knowledge (www,howtopedia.org). For this Platform we use Wikimedia.

WikiMedia : the foundation wich manage WikiPedia servers / bandwith and promote it.

MediaWiki : the software you are probably talking about :o)))

Cause of the potential risk of misuse of such technologies we decided to force the user to pass through a disclaimer validation process (to discharge us from reponsability in case of accident etc...). For implementing this I have to put a test (session + cookie based) to all articles. Where would be the best place to put this code?

Since all the article name is passed as a parameter to index.php ( aka: index.php?title=articleName , you probably want to add your code somewhere in index.php or eventually in your LocalSettings.php .

cheers,
