Yo!

I'm also trying to make a C++ chat program for my guild so we can coordinates attacks better in a game.
Problem is, I got no idea of what I'm doing.
I've studied C++ for some time and can do easy programs in DOS and such.
But I got no idea of how to make it interact with a server and then send messages.

I can make the login, easy!
But if you would help me out here on how to make it I'd be really glad.
(It's enough if the program is only in DOS, since that's how I want it, "easy and fast!")
So please master.. TEACH ME :D
