OXM - Some of your questions have been blurred together for the sake of efficiency. We're big on efficiency round these parts, as you can tell from the fact that it's 7.20pm and I'm still in this stinking office. If there's anything else you'd like to know, by all means throw me a comment. I can offer no guarantees I'll respond before (e.g.) you expire of old age and disappointment, but by the Gods I'll try.
