Peter Merel developed CVWiki which was an early WikiWikiClone released partially under the GNU Lesser General Public License, and Markus Denker then developed AtisWiki which was released under the GNU General Public License and based on CVWiki.

[5] It was replaced by the concept of wikis in 1999, and the development of UseModWiki started on October 11 as a simplified fork of AtisWiki.

[9][10] It was patched in July 2007 when Markus Lude took over the project of UseModWiki from Clifford Adams, with the release of version 1.0.1.

On July 20, "the PHP script" was then replaced by its own rewritten wiki software (phase III), currently known as MediaWiki, for better performance and functionality.
