The French Wikipedia is again available! Install the WikiTrust Firefox plugin, and navigate to fr.wikipedia.org to see it in action.
Note that WikiTrust is not necessarily available on the main page of Wikipedia; navigate to a page on some topic to see it in action.
Coming next will be the German Wikipedia (we hope by the end of the coming Weekend). We are also working on the English Wikipedia; we think we should have WikiTrust up and running on it by the end of the month.
