What is a “network”?

A network is a group of different, individual sites that operate independently but share the same player pool.  An example would be the “Winning Poker Network” consists of Americas Cardroom, BlackChip Poker, PokerHost, and YaPoker.  You can sign up to any of them individually, and all 4 sites share the same player pool.  Some of the main advantages of this structure are that each “skin” (individual site) may be able to accommodate different states or countries for legal reasons, and together they can provide a larger player pool with more traffic.
