There isn't a proper online sponsorship thing as far as I know, but if anyone wants to give me money for this worthy cause the best way to do it is either to give it to me in person or send it as a gift via paypal. Either way please contact me first via the usual gmail address or Livejournal, don't send any money until I've done the thing. If you're a UK taxpayer we're a registered charity and can get extra dosh if you supply your name and address including postcode.
Many thanks!
