What we could really use is some kind of prominently linked page with an
introduction to the whole idea of free content, and _why_ Wikimedia projects
are free content. Bear in mind that for a vast number of users, Wikipedia
will be the first free content project they have met. The en.wp article
[[free content]] is often used for this purpose, but it isn't exactly ideal
and a page out the main namespace would certainly be better.
[[Wikipedia:Copyrights]] gives a reasonable explanation of the rules, but
does little to explain why they exist, and why they are a part of our
mission.
