Foundation series
The SCP Foundation series originated in the "paranormal" /x/ forum of 4chan, where the first special containment procedure, SCP-173, was posted by an anonymous user in 2007. Initially a stand-alone short story, many additional special containment procedures were created shortly after; these new SCPs copied SCP-173's style and were set within the same fictional universe. A stand-alone wiki was created in January 2008 on the EditThis wiki hosting service to display the SCP articles. The EditThis website did not have moderators, or the ability to delete articles. Members communicated through individual article talk pages and the /x/ board; the website lacked a central discussion forum. In July 2008, the SCP Foundation series was transferred to its current Wikidot website after EditThis switched to a paid model.
