This brings up again the issue of whether we should
start registering
trademarks belonging to the Wikimedia Foundation. Without necessarily
resorting to threats of legal action, I think it would be far more
effective if we can tell people "Wikipedia is a registered trademark of
the Wikimedia Foundation" instead of just "Please do not use the name
Wikipedia on your website as if it was the name of your encyclopedia".
Trademark registration is something people will recognize and respect.
They will generally respond more quickly, and they will be more likely
to comply, even if the person notifying them is not in an "official"
capacity.
Have we tried telling them "Wikipedia is a trademark
of the Wikimedia Foundation" yet? How did it work?
Why do we think that adding the adjective "registered"
will make it work better?
