Just a quick note re: the 2017 encouraging editors’ example letter. I’ve gotten this twice, and frankly, I don’t think this is a higher tier form letter. I think it’s their standard. How was its categorization as “Encouraging Editors” letter determined?
The determination of what category something is in is user-reported. I don't know which page you're referring to, by the way. It's better to put questions like this on the "discussion" tab for a page, although whether someone will actually see it who knows is hard to say. --D. A. Hosek (talk) 21:29, 27 February 2018 (PST)
