Hi WF, You're still one more forum to lurk, one more collective mind to poke, prod and inquire; but I hope you'll soon become a friend. English isn't my first language and I've never tried to Write something in the web language. I suppose that will be a permanent barrier to parts of this forum, but I hope I'll find the words to discuss the subtler arts of transmitting a thought. And now that I've presented myself, it's time to lurk and learn. Let's see how you work, what you collectively believe, which of my questions you're tired of answering and which ones may light a spark of interest.
