That sounds completely different than the total control of the account you are suggesting. I also suspect that it would take quite an overhaul of the account options on the site in order to implement.
Regarding the continued maintenance of existing caches, we've had that discussion in our area in a couple of sad instances. In one situation, the family had no interest in keeping the Listings/containers going, so a few community members unofficially kept them going, but they eventually have reached the end of their cache life (in most instances) and have been Archived.
Philosophically, it seems the natural order of things on the site, living or dead, that cache owners come and go, and caches get replaced, new Listings get submitted, and life goes on.
Thanks James.... I love the alternate viewpoints. I guess it all depends on what and whose vision we follow. Gracias
