GNU Free Documentation License
The GNU Free Documentation License (GFDL) is a copyleft license for free content, designed by the Free Software Foundation (FSF).

The GFDL is a "copyleft" license, meaning the content can be copied, modified, and redistributed so long as the new version grants the same freedoms to others and acknowledges the authors of the Wikia page. Wikia content will, therefore, will remain free forever and can be used by anybody subject to certain restrictions, most of which serve to ensure that freedom.

Wikipedia, one of the web's most popular reference works, uses the GFDL. Using the same license as that site makes it easy for Wikia users to reuse the content from Wikipedia. You must adhere to the GFDL when using Wikipedia content.
