He didn't spit the dummy. He has decided to leave because he was put down when he didn't do anything wrong, I read the thread and he didn't say or do anything wrong and yet after it got a bit heated (again where he made no personal aspersions) most people that responded turned on him to some degree (unfortunately I wasn't on the forum at the time). Who is to know if he will come back, I hope he does, because he made it interesting around here and he is one of my buddies, but I don't blame him for wanting a break from this place after that.
That hopefully answers your question, and lets not turn this thread into some big debate, because I don't think it is required.
Nice that someone noticed he was gone though (genuine comment here, not sarcasm).
