Answer

Hello.
Everything written on the site on behalf of the site is written by me (M.A.). The username (="staff" or something else) is just a leftover from when the name was set, and I don't even remember what it is. As for the term "definitive rulings," I don't know exactly what that means. I write what seems correct to me, and whoever wants can accept it, and whoever doesn't, doesn't. I'm against accepting things just because someone said them.
