Pete, piss off. Macosal asked a polite question. I happen to know (a fair bit of) the answer, so I gave him a polite answer. I hope it helps him understand. I'm not pretending that I have sources for all of this. I'm not asking that it be added to the article. I'm sharing knowledge. It's something I do. Reject it if you choose. I cannot comprehend why you would, but people surprise me every day. (Oh, and there's little opinion in my post. Most of it is pure fact. A fact is still a fact whether it's sourced or not.)
