this is not a bannable offense. you can mute him:

To temporarily mute another player's chat, type the following into the chat box:
/mute player name

There is a space between mute and the player's name. The name must be typed exactly as it is, case sensitive. No one else will know that you have muted a player, this will last until one of you stands up

well that's good to know anyway. I sim race in league and we use a program called teamspeak. With that we can permanently mute the obnoxious people...

thx for the info, I will pass that on to ryan and see if it could be used for gpokr
