Wikianswers is part of Wikia, which aims to enable both the creation and organization of knowledge.
Wikianswers aims to collaboratively create the best answer to any question, by providing a rich set of facts researched from publicly available sources.
Wikianswers is a question and answer site inspired by traditional wiki principles of openness, transparency, and editability. Because of that, the content of Wikianswers is freely licensed. This means it can be re-used and re-purposed by others for free, and that the original authors of any answer maintain their own copyrights on their work.
Anyone can contribute to Wikianswers, even without registering.
Wikianswers enables editors to improve answers collaboratively, allowing the best answer to emerge from a process of community consensus.
Wikianswers aims to be an international site. Wikianswers is waiting to be expanded into 100 different languages, just like the rest of Wikia.
