That is correct. Here are the moderator capabilities from bb-includes/capabilities.php:
'moderator' => array(
'name' => __('Moderator'),
'capabilities' => array(
'moderate' => true,
'participate' => true,
'manage_tags' => true,
'delete_topics' => true,
'close_topics' => true,
'stick_topics' => true,
'move_topics' => true,
'view_by_ip' => true,
'edit_closed' => true,
'edit_deleted' => true,
'browse_deleted' => true,
'edit_others_tags' => true,
'edit_others_topics' => true,
'delete_posts' => true,
'throttle' => true,
'ignore_edit_lock' => true,
'edit_others_posts' => true,
'edit_favorites' => true,
'edit_tags' => true,
'edit_topics' => true,
'edit_posts' => true,
'edit_profile' => true,
'write_topics' => true,
'write_posts' => true,
'change_password' => true,
'read' => true
)),
You could add the permissions you for your moderator there, but it’s generally a bad idea to modify a core file. You probably want a plugin to modify the capabilities for your moderators. I didn’t see one specifically for that, but I did notice this plugin was added yesterday.
