The fact that FastMail management at that time made the (very) poor business decision to offer lifetime service for a one time fee is NOT MY PROBLEM.
Now, I'll just repeat verbatim what I said in the other thread.
> FastMail made an agreement - $15 in exchange for a lifetime member account.
>Now they don't want to honour that agreement.
>And they've created work for me: What to do about my father's email account?
>I have his email address as part of the domain that I have associated with my (legacy) FastMail enhanced account. They've discontinued family accounts for new signups.
