See Phab:T153147 for the relevant task.
Structured Discussion provides a well supported, wiki-integrated environment in which we can hold threaded discussions. In Judgments, Endorsements, and Preference, I described a JADE workflow that involved a "discussion post" between two users. I'm imagining that we can mint a Structured Discussion board as needed for discussions about judgments. These will help users use a central location to negotiate whether or not an edit was damaging or likely to have been saved in good-faith -- or if an article is C-class or B-class.
My two big questions are (1) can we mint a new Structured Discussion board for an arbitrary wiki entity and (2) will people find having a whole Structured Discussion board for discussing Judgments about a wiki entity intuitive?
