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.
