@feld @Tubsta I'm unaware of any such coops, but there aren't that many folks in my circles who fall in the intersection of technical competence and familial trust. Fortunately, the VPS requires minimal upkeep and I try to keep the domain-name registered as far out as I can, so, while my demise might mean she has to switch to something like gmail or a different mail provider, she at least has some time to do it.
