I have a forum. So far, I have yet to find out how to prevent "guests" from posting on the forum. It is supposed to be only registered users allowed to post. I am using "phpbb". Thank you.
phpbb permissions are based on each individual forum within your phpbb installation. So from the admin panel you will need to go to 'Permissions' in the 'Forum Admin' section, select the first forum, click 'Look up Forum' then make sure 'Post' is set to 'REG' from the Advanced mode. Then repeat for each forum.
Wonderful to know I can get my answers here on DP! Went there, done that...should take care of the guest comments (especially the rude guest comments...lol). Again, thanks for the help.
