Wow, this is looking really great.
I just tried it on my localhost and noticed when clicking into a Topic of a Forum in a Group (BuddyPress 1.7.2), I get this:
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title><br />
<b>Fatal error</b>: Call to undefined function bp_get_the_topic_title() in <b>/Users/MartinC/Sites/gaj/wp-content/plugins/wordpress-seo/frontend/class-frontend.php</b> on line <b>397</b><br />thoughts?
