Command and Conquer 4

I wonder how you talk to ur teammates about plan, chat during the match, draw lines on map & and send copy of it to ur teammates or play with cpu.

Any tips??

For talking or chatting, there is the ingame chatroom and voip. But you're better off using an app dedicated for that like xfire, skype, ventrillo, teamspeak and more. That way you will have more privacy and control with your chat.

You pretty much said the things that a team should do in preparation for a tourney. That's a good start imo. Speaking of preparation, here are two tournament training tip posted on the Home page:
