I tried this plugin out to add WYSIWYG to bbPress 2.0 (a WP Plugin!) post and reply fields. Works great!!!
I used this on line 25 $("#new-post textarea").cleditor();
Unfortunately, I was not so lucky in getting it to work for the buddyPress 1.5 (also a plugin) group specific forums.
Awesome plugin!

I found the problem with buddypress...
this plugin tests for is_single() before application of the editor. Apparently is_single() is false for all of the pages where one might want a wysiwyg editor to show up in buddypress.
By the way, you can put a comma delimited list of element selectors in line 25... might be nice to put this in a setup parameter so it doesn't get lost in case of a plugin upgrade.
example:
$("#new-topic-post textarea, #new-post textarea, #whats-new-textarea textarea, #post-topic-reply textarea").cleditor();
