Wikinews
Wikinews is a free-content news wiki and a project of the Wikimedia Foundation. The news articles are written by users working together with each other. Old articles are archived, and protected so that people cannot change it anymore, except if an edit request is given. Every article has a talk page where people can talk about the news in the article. The article is then peer-reviewed by an editor to see if it is ready to be published, and to publish it if it is.
