Agreed – it doesn’t work for me either.
Can’t find the tinymce function.
Fatal error: Call to undefined function wp_tiny_mce() in /var/www/joomladev/htdocs/blog/wp-content/plugins/bp-tinymce/bp-tinymce.php on line 44
Is this plugin still being updated? I’m still surprised this feature is not a default option eg. in network settings >> Enable MCE on buddypress
