(Projoy) This is probably true, but at least there's a chance one will notice an error. I'd be in favour of a mandatory preview, and I nearly always preview anyway. It's little bother.

Well, clearly we should then have mandatory preview on every game, and double preview on limericks. In fact, why stop there? The number of previews in a given game should be a parameter to be set at the beginning, based on the importance of avoiding error.

Should we even allow anything beyond preview at all?

(Darren) Indeed. Should we shut the whole thing down on Health and Safety grounds?

Maybe I should move over to a probabilistic model: you have a single button which, when clicked, may or may not post the move to the server....
