Choose a volunteer, then go to http://wikipedia.sourceforge.net . Browse the new codebase in CVS, and look at the files "Language.php" and "LanguageDe.php" for an example of what needs to be done for the translation. As soon as someone makes me a "LanguageFr.php" that's reasonably complete, we can move forward.
We finised translation some weeks ago. But it's seem the version we translated is not the more recent version... I'm waiting about Brion feedback.
