This plugin provides a BBCode-like filter for posts and comments. It does not use shortcodes. It does support multi-line enclosed tags. Most standard BBCode tags are supported. It also strips markup from RSS feeds.
This plugin adds support for video and audio shortcodes to posts and pages.\
If you have 'bbPress2 shortcode whitelist' installed, you can also opt to
allow them in comments, bbpress 2.0 forums and buddypress activity, group
forums and private messages.
