Use case would be where I'm moving a subset of users to a new server.
This subset of users is in a Cloudron group.
I export the list of user emails and use that to invite them to the new Cloudon instance.
@sam_uk I'm interested in this use case too. We want to incubate groups on our Cloudron until they've reached a size where they can afford their own.
I use Cloudron with Gandi & Hetzner
