The license WikiPagan uses grants free access to our content in the same sense as free software is licensed freely. This principle is known as copyleft. That is to say, WikiPagan content can be copied, modified, and redistributed so long as the new version grants the same freedoms to others and acknowledges the authors of the WikiPagan article used (a direct link back to the article satisfies our author credit requirement). WikiPagan articles therefore will remain free forever and can be used by anybody subject to certain restrictions, most of which serve to ensure that freedom.
