@mayel Thanks Mayel. In fact it was at webarchitects that I was disappointed to find no 'server admin-free' package for Mediawiki. They will host. But I would have to manage the apps/modules they were hosting. Too tech and time consuming for me. Content is where my time goes.
It would be helpful to know the other side - how time consuming/costly/ill-fitting would this kind of 'tech-naive' service be, for a coop that basically offers common-carrier hosting to tech-capable clients?
