+##Limitations##
+
+A user can belong to more than one peer, without any limitation. This fact may
+produce some limitations though, to FoD application. FoD uses polling for updating
+dashboard and let users know about other users' actions, who belong to the same
+peer. In order to fetch updates from all user's peers, FoD makes ajax calls for
+any one of them. It is recommended not to add more than 5 peers to any user,
+because it may cause malfunction to FoD application.
