pretty polite, friendly and erudite. Can we really ask for more?

Not a lot, I agree. As I said, by the time of posting I had retracted somewhat, feeling the tone sounded far too prescriptive for such a lively bunch of fellow nutters!

But nevertheless, I still think we can all help make it a bit more manageable by observing some of the common-sense ideas that have been aired.

My only other point is that I was speaking as "one of the class clowns" - if anyone thinks my hope is to edit out tomfoolery they must be daft. Please let's not let every thread get bogged down in snide jokes about the thought-police and so on - it will get very tedious very quickly.
