During the brainstorming phase of the project, we ran a small straw poll on what the preferred license for Wikinews content would be:

The content that is currently on the Demo wiki is in the public domain in order to facilitate the migration to any other license. In the straw poll, there is currently a small lead in favor of using dual licensing, but the opinions on what licenses to use differ: Some think we should dual-license as copyleft, others believe that we should allow non-copyleft uses for the sake of simplicity. The straw poll as such is not very conclusive.
If there are no objections, I will go ahead and hold a real vote on the issue as soon as demo.wikinews.org is moved to en.wikinews.org. However, please note that this is a rather far-reaching decision, so Board input would be appreciated.
Regards,
Erik
