:up: Incidentally, I wonder whether there's a difference between 'there's no doubt' and 'there isn't any doubt' (which I think I would be more likely to use in an informal context). :=?
I'd use 'There's no doubt [of/that]...', but sometimes (when there's no object of the doubt - but not always then) I say 'There's not any doubt'. I wonder whether there's any regularity to my choice.
