Thanks for your replies everyone. It's really helpful to know that you all think pretty much the same. I had suggested that they print off the form sign it and return it via scanned email and then post the original, but my beloved, being the typical lazy boy, decided that no-one would want to print it off sign it and scan it back to me!
Hearing that you all do the same as I had at first though backs me up, so again thank you!
BTW this site is fabulous! I have had so many questions and wondered where I could find the answers, I stumbled on you accidentally but you are now top of my favourites list...
