Lemongrove, I think maybe everybody 'cept me and you are busy this weekend. And I have four twitter followers and still don't "get it", so I'm not going to be much help. At 57, I'm right there with you in incompetence. So I'm bumping it up, in the hopes that it will keep it on top for a more twittery sort of person, and I'm repeating the website for the signatures (if it'll let me, I can't always make it like my links):
so that people don't have to go back to the first page to figure out what you're talking about.
Did you see the article in the Express about the cyberknife on 30 Sept? I've never read the Express in my life (I was googling cyberknife), and they couched the argument in political terms, but it was interesting just to see it in the media; it doesn't get much press.
