This plugin allows you to use Dokuwiki syntax for typing up your posts and pages.
WP-Dokuwiki is yet another markup plugin for WordPress. It lets you use Dokuwiki syntax in your markup. It currently works for both pages and posts. I will soon add support for comments as well.
The plugin is hosted at the WordPress plugin repository. You can browse the source code at http://dev.wp-plugins.org/browser/wp-dokuwiki. Please use the bug tracker over there to file bug reports.
