Hello there! Anyhow here knows how to make it like Member(s) can see threads posted by me on a specific forum section, and they can post thread. But can't see other threads posted by other user(s). They can only see their own!
In your node permission's for Members you will need to do two things. First off edit this permission. Revoke > View threads by others Then I suggest to get this addon View Staff Threads and edit this permission: Allow > View sticky threads Then I would sticky your threads or any other threads in that forum so users will only see threads are sticked. If you want to make it so certain groups can see all threads in that forum then edit this permission: Allow > View threads by others However, if you want users to view staff threads in general in that node then edit this permission: Allow > View threads by staff If you need any further help setting up permissions then let me know.
