I'd like to say that, assuming things don't go dramatically downhill from here, this thread should be preserved as a 'how to do it' exemplar. Lots of different viewpoints, many contradictory, but airing them in a considered and thoughtful manner. The occasional slip into abuse (or near it), which the abused calmly ignores or deals with quietly without getting into a slanging match.

Well done chaps!
