South Park Universe is a South Park cooperative writing fansite launched on March 28th, 2009. It is run by Shane Marsh and Schan Schan and has two published stories. The forum is divided into areas devoted to character development, story development and writing, art, and other areas exist for non-forum stories and general discussion. It has 10,500 posts and 40 members. It does not discriminate against genres, but debates arise when certain ideas are put forth.
After two years of inactivity, it was resurrected in April 2012 with a "clean slate" policy in hopes of gaining members who will introduce new ideas and developments forth.
