I have admired you in this field and Roger Federer in Tennis, who both had just lost the first ranks. <BR/>Through some of your screencasts, I especially love your way of competing, which is fair, gifted and tactful. <BR/>I am not sure if ACRush still wins the matches without pre-written codes, but your not using them makes me more admire you.
