Thanks for all your replies. I quite agree that making it available by email would drastically increase sales, however the setters are not on the internet and wouldn't know where to begin. I have offered, in the past, to produce an email copy for them, using my email address, but I think they're scared stiff of "all this new-fangled technology", and of people getting a copy without paying. It's all very silly, because most people return their entries with the money, and you haven't lost anything if they don't.
