Thanks Kevin, I think I will use the url method. My initial worry with using that
kind of method is people deciding to play around and authenticate other peopl while
they're at it, but I can use a one-off password and unique ID to get around that
problem.
It's a shame that email clients that can't handle html tend to treat it as text -
it'd be nice to provide a form for those with, then a nohtml tag with the url inside
for those without.
