Where the setting to putting whole group on post moderation?
where is this setting to put everyone in a group to have their posts moderated, thanks
in the users and groups usergroup setting
there is nothing there, you can ban them from posting but it seems you can only set individual users on moderation
See moderation options.
does that allow them to moderate?
No, it sets them to BE moderated. If you tick moderate new posts then all new posts by that group are moderated. Etc.
