The only permissions relate to "access" which is to see and read the board. "Permissions By Board" states
Here you can set whether a board uses the global permissions or has a specific permission regime. Using local permissions means that for that board, you can set every permission for every membergroup.
But that is untrue. The only options are: Normal | No polls | Reply only | Read only . If I click on a Board name, nothing happens.
I'm looking at the url "... .smfforfree2.com/index.php?action=permissions;sa=board" which I get with Members >Permissions : "Permissions By Board". Nowhere on the screen can I select "local permissions".
