Actually, my comment above was addressed to Stifle, who locked the article. So I have no idea who you are talking to. Bfigura: in case you did not notice it so far: I do not care about non-serious explanations as they are by definition invalid, just like the many non-binding ""regulations"" that Dicklyon has been trying to misrepresent as obligatory. But when you actually go on and read them, they usually say something like ""this is a recommendation only"" or “this is a style issue that editors are free to choose” and so on. So spare me, will you. Thanks.   "
