I’ll give you an example. We created a group for writing documentation in a private category and then migrating to a public category for publishing. Quite a few documents are also migrating over from a markdown website.
Ideally, trusted group members can move these document topics over as opposed to admins & mods. We have no need for staff assistance if we can help it; our group is ready to moderate itself and it’s topics..
Also, a lot of our topics are old. We created a user “docbot” to assume ownership of these documents. Ideally we can assign our documents to this particular user rather than it being myself or whoever else is copy-pasting in the markdown. It would be ideal to let group members change ownership of these topics since they have nothing to do with forum staff.
