Winsock Server With Multiple Connections Support

A Non-block winsock server that can handle multiple connections. It isn't finished yet, but i'm hoping finish it soon. It currently is just a console application that shows what the user sends & detects new connections / disconnections. I will soon add suport for linux and add functions to send/broadcast messages. I'm new to C++, besides the hello world app this is my first c++ proggie. I'd appreciate some feedback very much. And like to hear from you how I can improve my server (Its killing my cpu :), would it be better if I'd ran my server in a seperate thread???)
