Don't argue with me. Just read the references as this is extremely well documented and very well known by all but the youngest kids out there.
Take it easy on the newbies, Bee. You've been a great asset around here for a long time and I know it's difficult to remember what it was like starting out. Try to brush away the cynicism and remember that sometimes a question is just a question.
