Full Chat and Winsock Tutorial

This is a Winsock Tutorial I created. It is a reasonably nice chat client / server, save chat session text, change username, etc. This is in response to someone else's Winsock Tutorial, I made this one just a bit more advanced, but left a note besides almost every line of code, and added more features. If you read this code, you will be on your way to making great client/server applications guarenteed. Enjoy !
