This forum isn't an authoritative reference or a peer-reviewed academic environment. It's a forum. You'll get good accurate information, inaccurate information, something in between and information that might be thought "bad" today only to be "accepted" tomorrow. It's up to you to sort it out, just like in the rest of the world. If you don't want to exercise that sort of judgment, arm yourself with whatever comprehensive reference book you prefer and choose to believe it all. But don't rely on two, because they'll contradict one another... then you'll need a moderator again. Darn! Gathering information and making your own informed choices seems almost inevitable, huh?
