is there any way to deactivate logging-in and registration so that any one is free to make comments on my forum boards without having to register? i want an open forum.. no membership.. is it possible?
Yes, you can disable the user registration in Dashboard > Forums > Settings > Features Tab.
Then disable the user registration in WordPress settings: Dashboard > Settings > General Tab
Then remove login / register menu in Dashboard > Appearance > Menus admin page. Choose the [wpForo navigation] to access wpForo menu.
Then enable guest posting for each forum, here is the instruction: https://gvectors.com/how-to-enable-guest-posting-on-wpforo-wordpress-forum-plugin/
Thanks a lot Robby...
