PikiePikie is StevePike's implementation of a WikiClone, based on MartinPool's PikiPiki but extended in many ways. It's written in the PythonLanguage. Development started in December 2000, and I am hard at work adding features already available in the more mature scripts.

You can find the current status of this project at http://pikie.webbing.nl/cgi-bin/pikie.cgi?HomePage (including a list of enhancements on http://pikie.webbing.nl/cgi-bin/pikie.cgi?DevelopmentWebLog), and the latest version is always available for download from http://pikie.webbing.nl/cgi-bin/pikie.cgi?DownloadPage.

It's most notable addition to the usual wikiness is the ability to put a WebLog on any page.

News as of February 2002: 'skins' have been implemented and PikiePikie has acquired a default skin. Feedback most welcome on whether you think this skin works -- StevePike.
