When it's too obvious we've been too careless to give out information which i agree with but when another mod has closed/deleted a thread other than ourselves it's not always clear to us either why the thread had been edited, thus we have to ask the mod who did so. That's a process that some members don't have the patience to wait for.. We've just recently had an agreement we're going to be generally better to explain what happened with members threads via Pm's and warnings mostly.
