BuddyPress.org

What versions are you using? When I hovered over your signup I saw that you still use wp-signup.php rather than the buddypress /register. Also tried using /register on your site, but that gives a blog post..

Also, your links redirect to your other site (siliconangle.net), so I can see that when you login to siliconangle, your not logged in to rizzn.com..
