Just below the title bar where you type your post, there is a little icon that looks like a checkers board (heh heh heh)
Click that and it takes you through this nifty little program to help you post your game. The mouseover will say insert position or game.
Sorry ifthis has been posted before but i cant seem to find out how to post my games like everyone does in thatchessboard thing where you click the arrowsto see the next or previous moves. Any help would be nice.
