TUTORIAL.se soon ready but what about the Copyright?

Hi, We are soon, I hope ;-), ready with the Swedish translation of the TUTORIAL but I have one question about the copyright. The copyright for the English version is FSF but for the other translations, that I have seen, the copyright holder is either a person or both the FSF and a person. No translation has only the FSF as copyright holder. How should it be? Can I just write that the copyright holder is FSF or should I include myself as a copyright holder as well? Are there any legal problems with that? Should there be papers signed etc. And what about the people that has helped me with suggestions, proofreading etc? Yours -- %% Mats
