So, how do you explain that NIC France accepts the use of linux.fr to someone who pretends to be the author & proprietary of the name "linux" and who IS NOT Linus Torvalds?

This reminds me of the times when people on the list accused other list members of being closet spammers. At the end of the day, this kind of public accusation is a waste of our time because we don't really have the tools to determine which side is telling the truth. In this case, I am fluent in French, and I spent 15 minutes or so, browsing http://www.linux.fr. It appears to be a legitimate *public* portal for people who are promoting the use of Linux in the enterprise. Nothing on that site claims authorship of Linux and I even stumbled across one forum message that made it clear that Linux is based on the GNU toolset. What is clear is that both http://www.linux.fr and you http://www.fr.scguild.com are trying to offer directories of IT consultants among other things. Could it be that you would rather divert the common resource (a domain name) for your own profit rather than let someone else do the same? Hopefully you and AFNIC http://www.nic.fr can take this silly dispute offline where it belongs.
