For future reference, this is what you have to do now:
Change "Configuring privileges for..." from "Global" to each category. You can then remove all "Guest" privileges.
I would like that new posts from normal members need approval first, but posts from the "staff members" should pass through. I think the post queue currently applies to all users. It would be great if we can set that for each user group instead.
Makes sense. Please open an issue on our github.
