I will try to put this better, I need to delete yahoo answers for my friend How do I do that without ..?

messing up her email. I've been staying with her for awhile and I am leaving next week. I will not have access to a computer for awhile. I was teaching her some things about the computer and on her email we set up a yahoo answers account. She doesn't really use the computer except for staying in touch with family and a couple of newsletter's and hasn't liked the little I've shared with her on YA. We all know people can be rude. So she asked if I could" remove" it since she won't be using it I can't seem to figure out how. Can anybody help. I'm hoping I don't have to have her change her email.
