I need to block all "Guest" posting. Some of my forum categories are allowing guest's to post and some don't. Is there a setting to block all guest postings? Thanks.
Login onto your admin cp, look for forum management and choose permissions.
And make sure the appropriate permissions when you edit the "Unregistered/Not Logged In" group in Admin CP --> Manage Groups are disabled (like Can Post New Threads, Can Post Replies, etc)
