DJA - I don't have any particular IT skills, I just created the PDF from the Exact Editions page and copied the URL. However, its extreme length would seem to suggest that there's some kind of inbuilt barrier to non-subscribers or indeed perhaps to anyone trying to copy the link. It worked with me, i.e. I sent myself the link and clicked on it and it worked, but, as I say, I suspect there's a secret ingredient in there somewhere preventing mass copying. Oh well, worth a try. Great that you're offering an alternative service for all Speccie junkies;-)
