This plugin is designed to safely allow bbcode shortcodes and other 
safe shortcodes to be embedded in bbpress topics and replies and also 
blog comments. You don’t wan’t users entering shortcodes such as 
[bbp-login] in the middle of their reply.
It doesn’t actually implement the shortcodes though, 
for that you need a separate plugin. I recommend my own bbPress2 
BBCode plugin, as this is fully whitelist aware, in that it also 
parses the contents of the shortcodes, so [b][bbp-login][/b] also 
gets parsed for safety. Something that doesn’t happen with non 
whitelist aware shortcode plugins.

Still working

This plugin adds creates a whitelist of shortcode tags that can be applied to comments, bbPress and BuddyPress.

This plugin adds support for bbcode markup to wordpress, bbpress and buddypress. 
It integrates with the ‘bbPress shortcode whitelist’ plugin to provide a safe 
way of enabling BBCode without giving your users access to all shortcodes.

I have enhanced support for the [url] and [quote] tags, and added potentially 
useful css style class names in the html output of the tags, to allow for 
exciting theming potential.
For example:
<pre><code>[quote=NAME]QUOTE[/quote] 
</code></pre>
will render as:
<pre><code><div class="bbcode-quote bbcode-quote-NAME">NAME<blockquote>QUOTE</blockquote></div>
</code></pre>
Or if NAME matches the login name of a user on the system, it will render as:
<pre><code><div class="bbcode-quote bbcode-quote-user bbcode-quote-NAME">DISPLAY_NAME<blockquote>QUOTE</blockquote></div>
</code></pre>
Where DISPLAY_NAME is the display name that user. With BuddyPress installed the name 
also becomes a link to their profile page, otherwise if bbPress is installed, it becomes a 
link to their forum user page.

bbPress2 BBCode

This plugin adds support for popular bbcode forum code to posts, comments, pages, bbpress 2.0 forums and buddypress activity and group forums.
