I’d like to create a category and set permissions so that only users with a certain trust level (say, 3) can post in that category, but everyone can read. That is, set per-level permissions.
That’s easy! Give the “See” permission to the Everybody group. In fact, the
howto category on Meta is set up like that.
See for everybody ok, but how do I set “post for level 3”?
From the drop down, select Trust Level 3, and give them Can Create/Reply/See. So you should have two permissions, one for TL 3 and one for Everyone.
It’s fine. When I set the permissions for level 3, it is intended for level 3 and above? Or strictly level 3?
TL 3 and above. I believe Staff and Mods can access it too, regardless of their TL
