First; cool name if that's who I think you're referring to.
Just click on the Friends tab to the right of the chess board. There you'll see a list of friends on live chess. Click on their name for a chance to challenge them.
Or you can go over to the main chat tab and click on someone's name there and challenge them as well.
How do you challenge someone to play a live game? When I want to challenge someone but want to change the time or other settings, I can't do that. The only options seem to be rematch (if you're playing someone), or correspondence chess if you are not playing them. Putting up a challenge means that you have to hope the other player can beat everyone to selecting your game.
Thanks.
Bill
