I've created a custom user group for some Joomla 3.x websites which allow certain users particular administrative privileges, but only to the functionality they require (I trust my users', but I prefer fewer opportunities for exploits or accidental breakage).
One permission I need to grant them, is the ability to check-in articles that other users haven't correctly closed (where the padlock appears beside an article, preventing multiple users from editing the same item simultaneously). Currently, though, only Super Users are able to do this.
How can I give a custom user-group this click-on-the-padlock-to-kick-them-out functionality without granting them entire Super User privileges?
