1) I have created a group called "Admin messages" and assigned members to the group.
2) Next I changed "Post reader" and "Private Post Reader" to "blog role ignored" in "Exclusive sections" for the category "Admin messages"
3) Now these (private) admin messages are not be visible to anyone. Next I want to make them visible to the Admin messages group. How? I tried Groups -> Section Roles -> Category Roles -> Admin messages category: Private Post Reader = Admin messages
Those posts never show, though. Neither in the categories list nor in the archives.
What am I doing wrong?
