The new Google Friend Connect “social bar” adds basic social functions: sign-in, site activities, comments, and members into a small strip that appears at the top or bottom of your website. With the social bar, visitors can:

• Join or sign in to your site, view and edit their profiles, and change their personal settings.
• View recent activity on your website, including new members and posts on any of your pages.
• Post on your wall or read and reply to others' comments.
• See the other members of your site, check out other peoples' profiles, and become friends. Users can also find out if any of their existing friends are members of your site.
