Oh, I wish! Unfortunately, my OH has a pathological suspicion of doing such things on the net - something which I find difficult to argue against and, for the sake of domestic harmony, wouldn't dream of trying to do so

So, snail mail it must be.
(for those of you who don't know, if you do it by post you must first request the official application forms from GRO - they'll send you up to ten of each type - B, M, or D - in one go: thirty in all).
