There had been some talk about playing chess on the air. It was a topic on this forum a while back.
AC2Z went ahead and created a group to start a chess net. If you want to find someone to play, you can set up a game thru this group.http://groups.yahoo.com/group/Radiochess/
It does not necessarily need to be by code, but that is my preference.
Hope to hear from you soon.
