Maybe MB could give Carl a simple power of attorney over his internet site. With a simple POA you can restrict it to something specific, it's not the more encompassing power of attorney over all of your affairs. I don't know if giving the authority over a site is possible with a POA. It isn't just for after death, people who are senile or whatnot and can no longer handle thor own affairs, a POA is often given to a family member or another trusted person.
