Hi Prathap, Why don't just create a vertexes for non registered friends and mark them as non registered. And when new user is registered just check if vertex for him already exists and mark that vertex as registered.
In this way you could filter unregistered users whenever you don't want to see them, and can avoid complex merge operations. Is such approach possible in your data model?
