Signing a petition for someone else

[carolineb]

Hi I have been runnign a peition online but have some people who are already on my database who want to sign it - however they have emailed me so I just want to go and sign them up. Is there anyway I can do this from their contact page rather than have to go and look up all their details (I always ask for people's addresses when I do a peition) and then enter them all again to sign them up through the sign page.

Thanks
