Wikia

Wikia (formerly Wikicities) is a free web hosting service for wikis (or wiki farm). It is normally free of charge for readers and editors, deriving most of its income from advertising, and publishes all user-provided text under copyleft licenses. Wikia hosts several hundred thousand wikis using the open-source wiki software MediaWiki. Its operator, Wikia, Inc., is a for-profit Delaware company founded in late 2004 by Jimmy Wales and Angela Beesley — respectively Chairman Emeritus and Advisory Board member of the Wikimedia Foundation — and headed by Craig Palmer as CEO.
