Of course, there's no way of knowing whether these nameless GUEST poists come from lots of different people, or from just a few, or from one person.

Peole have an automnatic tendency to assume that, in a single thread, when they get into an argument with GUEST, it's the same GUEST who reponds, but there's no reason that should be true. On occasion we've had quite sharp squabbles between successive GUEST posts - but of course that doesn't prove anything either way.
