Profile2 is a complete re-design and re-development of the existing Profile tool in Sakai. It gives you more of a Facebook style interface for editing your profile. In addition you have a comprehensive set of Privacy controls to allow you to choose who can see what part(s) of your Profile.

With Profile2 you can post updates (integrated with Twitter), search for people with common interests, view their profiles, view their connections, add them as a connection, send private messages, upload and share pictures, and much more.
