If you want to test the new Pathfinder Alpha rules but have a hard time reading English, or if you want to test those rules with players who wouldn't understand the English version of the rules, you can find a fan-made translation of the rules in this discussion. This is only a first version of the translation, and you are welcome to report typoes and errors either on that forum, or directly by mail (see the address on the document).
My goal in translating the rules is to allow more people to playtest them; I do not intend to get any money out of it. I checked with Black Book Editions (who are in charge of the French translations of the Pathfinder adventures and sourcebooks) and they do not mind that this document is publicly available. If Paizo feels that this is not a good move though, they just have to send me a mail and I will make sure that this document is no longer available - with no hard feelings from my side. As written above, my goal is help the playtesters and not to hinder Paizo in any way.
Happy gaming!
