I implemented your product last evening. Everything seemed to go smoothly, except two issues.
1. Why does the Twitter registration-login automatically sign a user in on clicking its icon, instead of first showing a prompt that asks the user if they're sure they want to allow and connect with Twitter? Linkedin and Facebook were fine.
2. Why does the black menu bar not show any menu on mobile? I'm using Galaxy Note 3. (This may be a BuddyPress issue).
Feel free to sign up there using your social logins. The site is still in beta mode and I can remove testers later.
