I understand all of this, and agree with 99% of it with one exception. If a seller, for example is selling a brinly plow and you're not sure it'll fit your specific machine, if I'm understanding correctly, it is not ok to ask within that For Sale ad if it will fit a certain machine? The info is pertinent to the post, relevant to other users, and not really "chit chat". Just curious, not trying to start or egg on anything
