The User Connections plugin shows to users the web of their Social Graph, their shortest connection paths with other users and also how users know each other.
         The Network Span widget on the user homepages enables the users to see the depth of their Social Graph by seeing the number of 1^st level, 2^nd level and 3^rd level contacts. This block will further lead the users to explore these contacts. The Connection Path widget on the profile pages of users allows others to see the shortest connection path with them in an illustrative manner, along with the relationships between the connections.
       This is a great plugin to build social networks & communities and users can figure out who they want to be friends with. The User Connections plugin allows users to expand their networks and build relationships. It provides a good starting point to initiate communication between users.
