@Dwenaus, Thank you, that was something I was looking for.

Actually my goal is to have functionality as lautering described: “It would be nice to have an option in between like you suggest — read, but not write. A group where the content is public but joining is invite-only.” Unfortunatelly I’m not a skilled BP programmer, but if somebody could give me an advice how to start, I’d appreciate it a lot.
