Interesting case. Should access to a deceased persons' email account be
allowed to his family. For access to a Yahoo Account only the person
who owns the account can give permission, and as that person is
dead...it is a bit difficult...to say the least.

P.S. Mind you, I thought that every Tom, Dick or Harry had access to a
Yahoo email account...but there y'are...what do I know...:-)
