I have made a mess of things while trying to simplify.
I let a domain name expire that also had a custom email address attached to it and according to my domain registrar, lost both to a third party who scooped up that domain name so I no longer have access to it.
Therefore preventing me to do what I need to do with some of my Apple devices and old Apple ID.
Henceforth, this current domain, chrisdenbow.website and its associated email address, hello [at] chrisdenbow.website is here to stay forever.
If I want simplicity, then I really should take a few steps backward and just go analog everything and I am tempted to do so! (not yet.)
