Recently there have been well-reasoned calls to give users blunt feedback when they have strayed. It came to my attention that the wiki has no built-in feature for this social interaction, only the reverse. I have implemented a user script that allows you to chide another user for an edit. For example, I stridently disapprove of this edit from a year ago:

1. Click the “Chide” button on any edit in page history:
   
2. Click the “Chide” button to confirm:
   
3. Observe that the user has been chided:
   

To install this feature, add the following code to your user script page:

// [[User:Minh Nguyen/chide.js]]
mw.loader.load("/w/index.php?title=User:Minh_Nguyen/chide.js&action=raw&ctype=text/javascript");

I hope this enhancement improves the productivity and rectitude of our wiki documentation efforts.
