What is "wakkawiki"

WakkaWiki (often shortened as Wakka) is a very small wiki engine written in PHP that is easy to install, hack, and maintain. It was originally developed by Hendrik Mans, creator of the PlanetCrap discussion community, with help from Carlo Zottmann.

As of September 29, 2004, its website was taken down and the project was stopped, although a large community of contributors still actively posted bugfixes, extensions, and new functionality. WakkaWiki saw most of its contributors migrate to one of its forks.

The focus of WakkaWiki was on simple and therefore extensible code. Thanks to the simplicity of its design, it spawned several forks, sharing the same ancestry but pursuing their own vision. Many of these forks include scripts to upgrade from previous WakkaWiki installations. WakkaWiki has spawned at least five forks: CitiWiki, UniWakka, WackoWiki, WikiNi, and WikkaWiki.
