When invite-only is set, users cannot join unless they are invited by an operator. In Channel List, invite-only rows show a +i badge; non-members see Request Access... instead of Join and can send a knock request with an optional message.
Usage
/mode +i — Enable invite only /mode -i — Disable invite only
