The primary power of the s3x_NETWORK is that users can move across the network and have a seamless experience. Once they 'own' a user name on one site in the s3x_NETWORK, they can use it anywhere. Users can also have multiple profiles. So they may have one profile that presents them as a top, and another that presents them as a bottom. While they'll pick a primary profile for each session, all the profiles will be "online" and there will be a unified inbox where they can receive and send messages for all their user profiles simultaneously.
