"Directory" is the section of the site that specifically lists the people that are members of the site and who have set up custom profiles on the site for the benefit of file sharing, community/groups, and blogging on various topics. All users can set up a profile with a photo, bio, past employment and education history, and even ‘interests’. Once a user has a profile set up, you can add people to your contact list or search for other users by clicking on ‘Find Contact’ and then specifying the pertinent search criteria to locate that person.
