What does "can view threads" mean exactly? (Its in group permissions). Stupid question, I know, but its a new addition to MyBB, so I just wanted clarification on what it does.
Exactly what the name implys, if it's set to no. The selected usergroup will see a no permission page when trying to view a thread.
Basically it allows users to view the thread list of a forum, but not view the posts inside them.
