Wacko Wiki

WackoWiki is a PHP/MySQL based wiki engine forked from WakkaWiki.

Core features:

all features from WakkaWiki, including installer & upgrader (because it is really a fork from it)
clusters & relative addressing
page watching & email notification on changes/comments (simple diff included in email)
completely multilingual (RU,EN,ES,DA,DE,FR,NL,IT,PL,ET,PT,BG included in R5.4. Creating new language scheme seems to be very easy -- we have got most schemes from Wacko users)
enhanced WhatYouThinkIsWhatYouGet editing -- table markup, OpenWiki-compatible markup
Links can be CamelCase or FreeLinks
powerful diff between revisions
several levels of caching (backlinks, pages) bring significant performance gain compared to Wakka
automatic Table Of Contents generation
on-the-fly correction of punctual typos & spec. characters
design themes (skins) support (3 themes in package already).
