Hi, if you have xbox live and play halo 2 on it and you know how to host games under opti match could you please3 tell me how to do it. I know how to create a party but i don't know how to host the game so that any one can join by searching through opti match. I also realize that most of the games are random sites, but i have the official stratagy guide and it says that you can host under opti match but it doesn't tell you how to do it.
