After the switch to Creative Commons BY 2.5 license, there was some confusion at de.wikinews how to explain the new retrictions to those who want to mirror or spread Wikinews articles. As far as I have understood they have to give attribution to "Wikinews", provide a link to the license and show that the original content was released unter CC-BY 2.5. Please correct me if this is not correct.
Some suggested to create a site on meta to write more precise intructions for those who want to spread Wikinews content. There we could write the texts of sites like MediaWiki:Copyrightwarning and Wikinews:Copyright or Copyright FAQ and translate it into all Wikinews languages. With respect to license issues all nessecery informations needs to be correct and the same in all versions, because all content is released under the same license. The sites which will be written at meta could serve as frame. Local communities can add more information if they want to. If nobody is interested in a site like this, I don't start it. I've seen that the Polish community provides a link to the polish version of the CC-license. Most of the other versions provide a link to the US-Version of the CC-license. I don't know how big the differences are, but I think using the US-Version might be correct.
