I set up the global permissions just fine, but I can't seem to edit a forum. Guests can no longer post, which is good. My announcement forum however, won't let me turn off members starting topics. When I uncheck the box in regular members to turn off starting topics, then all usergroups are denied posting throughout the entire forum. How can I remedy this?
When you go to Boards>Modify Boards. You should see your board and then a link that states permissions. Select modify to edit a particular group's permissions for that board.
