inviting existing users is a good feature that helps to have richer discussion . but when the “must approve user” option is on, this option will be invisible to others.
the requested feature is just to disallow the invitation of outer users when “approval” is on.
I confirmed this is still the case. When the must approve users admin setting is enabled, the topic Share button loses its Invite button. So users can’t invite existing users to topics in this way which does work when the setting is disabled. (Well they can, but they have to copy the link and get it to the invitee that way somehow)
I am curious to know how many people use the invite system in this way. Is it common?
