The international language editions of Wikinews are still in beta, but some of the other language version have already moved one step closer to getting out of that state - they got a license. Now... This is not a good thing.
The Spanish, Serbian and Romanian editions are all licensed under the GNU FDL, and the Japanese edition is licensed under CC-By. That's due to the nature of the Japanese law, which, according to some juristic analysis, doesn't allow to release content into the public domain. That's not such a big problem - first of all, it might be possible to relicense the content under CC-By-SA, or simply ask the contributors to relicense it - since this is a new project, there aren't too many people to ask.
But, back to the topic. The 2.5 Creative Commons licenses allow to give the attribution NOT to every author of the article, but to the whole project - just check 4(b) of http://creativecommons.org/licenses/by/2.5/legalcode (same applies to every other CC license).
This allows us to finally license our content under the CC-Wiki (that's what we could call CC-By-SA 2.5) license - now the basic questions are:
1) Do we need to license it right now? 2) Will we really choose CC-By-SA 2.5, or some other license, like GFDL or CC-By, for example? 3) What should we do about the Wikinews projects which already have a license choosed?
