GeboGebo

GeboGebo is an OpenSource Wiki written for the tdbengine.

It stores all pages and data in a local database structure (no SQL server is needed), and thus provides fast access to it.

It has a built-in indexed fulltext search, RSS-Feeds, macros and plugins. It supports very fast (thank god for a database) AutoLink, PartialPageEditing and EmailNotifications.

Since tdbengine is a propriate database management system which might not run on any web hosters servers, an entirely free hosting service for GeboGebo wikis was started on http://wikihost.org
