Hello, i have recently started learning how to write multiplayer games, I have purchased Networking with Java (WROX) and the Multiplayer game programming book. These are great resources and im learning from them, but i was wondering where some good online sites are. I want to get a good understanding of sockets, etc. Thanks

Seems to me that those books ought to provide a pretty good overview of Java sockets...

You might want to take a look at javaworld (if it''s still online) and do some google searches too
