I've noticed that when I play online, no one chats. I know it's not required or really necessary, but it makes it more fun. I was playing last night and was "talking" to people and I was just ignored. Nothing lame or mean, just like "Now I know how JFK feels" after getting my head blown off. I also think it helps to keep in touch with your teammates. Maybe it's just my strange desire to belong....please accept me.....poop....
