@rod Yeah, the request is appropriate. In fact, people will be invited to groups. There won't be a lot of requesting to join at first...
I figure this is the functionality I want:
When a user signs up on my site, create the forum (NodeBB) account. (Is that necessary?) This will give the user on-site messaging with other users.
When the user creates a group on my site, create the associated group forum. Set user as owner/admin.
Allow other users to join that group by invitation from the owner.
When a user closes his account, close the forum group and archive all material.
When a user leaves a group on my site, disconnect them from the associated forum as well.
I'm wondering if Muut would be better for this kind of functionality...
Any and all opinions requested and appreciated!
