Go to Gmail.com, click on Create An Account. Create your new Gmail account. Have Gmail fetch your AOL email. You set this up in Gmail Settings. Add a signature to your Gmail account saying your address has changed. Reply to all email from the Gmail account. Eventually, you’ll be able to stop the AOL forwarding as all that will be left will be junk email. Mark all junk as Spam. Gmail has an amazing spam filter.
Voila! No one will call you Grandma/Grandpa because of your AOL email!
