I really think the best thing is to skip over the GUEST (nameless)posts. It's a pity because, among the various people who post that way, there is at least one and perhaps more (how can one tell?) who has things to say that can be worth reading.

But reading and responding to such posts is merely encouraging the silly bugger to continue playing this silly game. If we could only ignore such posts maybe the person or people concerned would give up on it, and post in a more courteous and helpful way. As has probably happened a good few times in the past, and noone the wiser.
