WP-MediaWiki

WP-MediaWiki adds a subset of MediaWiki markups to WordPress.
Currently, the following MediaWiki markups are supported.

• Bold
• Italic
• Heading
• Lists: Besides the list markups come from MediaWiki, I also added a continuation markup such that users can put preformatted text in a list item.
• Tables
• External links
• WikiLinks: the wikilink will link to Wikipedia by default, you can change the wiki site in the admin option page.
• Table of content
• Horizontal line
• Preformatted text

For more information about MediaWiki markups, please refer to http://meta.wikimedia.org/wiki/Help:Editing.
