That's alright. ;) I don't think it's going to matter much in the long run, anyway. Everyone's going to be both a client and a server at one point, and we'll also eventually have to decide which of the round one clients will be playing round two servers to which of the round one servers, if that made any sense.<br/><br/>Basically, though, imagine the Server as a person playing the Sims (they can modify things within the environment or build stuff, but they can't directly interact with anything besides deciding where it should go) and the Client as the Sim itself, able to interact with machinery and stuff, but they can't build things or change the environment. So Lily can buy and put down an Alchemiter (you'll see) somewhere in Phine's house, but only Phine can actually use the device.
