Groups and permissions

How do permissions work? Everything is restricted to groups. A thing with no groups ticked is visible to everybody; tick some and only those groups can see it. Signed-out visitors count as being in the Guests group rather than in no group at all. Administrators How do I make a forum only staff can see? Edit the forum, and under "Who may read it" tick the groups allowed in. Everything follows — the index, search, activity, streams and widgets all stop showing it to everybody else. Administrators What happens when I delete a member group? Its members move to the default group so nobody is left without one, and every restriction pointing at it is removed. Without that second part, a page restricted to a group that no longer exists is restricted to nobody. Administrators Why can I not see club groups in Admin → Groups? Every club owns an automatic group, which is how its content is kept to its members. They are hidden from the Groups screen and from every "who may read this" list on purpose, and cannot be picked as ordinary groups. Administrators Can I get back a topic somebody deleted? Yes. Admin → Deleted content holds soft-deleted topics, posts and application content, and you can restore them. Uploaded files are kept too, so a restored image is not a broken one. Administrators What is the difference between hiding and deleting a post? Hiding takes it off the page but leaves it readable by moderators, so there is a record of what was said. Deleting removes it for everybody, moderators included, and is recoverable from Deleted content. Administrators
