Somehow I have managed to lock some of the comments whose name I want to change, but not all of them, so I can’t do a global change. If I go one by one (there are over 200 of them…), I can change the ones that aren’t locked, but not the ones that are. How do I easily find the ones that are locked and unlock them? The “Make this setting default” box is not checked on any of them, so there’s nothing to uncheck.
