How to change my email address to reflect name change?

I've changed my name, and am going through the "telling everyone" stage. I'd like my Yahoo email address to reflect my new name. Can I do this without actually canceling the existing one and making a new one ? I don't want to lose all the stored mail I have in this one.|||You can create an alias, but if you want your main screen name to be this new ID you're trying to think of...sadly, you have to start from scratch. I've been through it 6 times lol.|||That's because you've been perving on people and your account got banned, James.
