TigerWiki was a wiki based on the last version roWiki of Marc Rohlfing.
TigerWiki is written in PHP and it's very light weight (principal code less than 13 KB). It aims to be a minimalist, functional and simple to use system based on roWiki (Which begin to be a ghost on the web).
Here's somes functionalities of TigerWiki :
Standard compliant : XHTML (partialy true) and CSS Compliant.
Automatic backup : Don't lost any important data due to bad handling. All pages, after modifications, are classed in a easy to access history.
Password protection : Allow modifications to pages only if a password is given.
Simple : You will be impressed by the simplicity!
Free (and open-source) : Not question to take-out some dollars from user wallet. TigerWiki system is completely free, modifiable and reusable (by quoting sources). Even the technical support is free, with a smile!
WiKissMe?: http://www.wikissme.org - a derivative from WiKiss? and influenced by TigerWiki/LionWiki. It is a personal content management system featuring plugins, blog, comments and captcha modules. Supports templates driven themes.
