No need to deregister at all RPG. If everyone who had mildly upset Scunner had to leave - including me about 6 years ago - there would be few members left. All you have to do is say "Sorry guv" and then not ask about weather in May, nor the price of Efes, for a few weeks and everything will be fine. But, I must say, that "interesting and intelligent" is not exactly the way I would have described your questions.
