Mike Ferrell at Cleantech is having a few problems with his website at present. The site is down and he can't receive emails either.
He hopes to have things sorted within the next two to three days, but he asks that if you need to contact him, please try
mikeflys@tiscali.co.uk and you should get through.
If you've emailed him over the last few days, I'd suggest you re-send to the temporary address - just in case!
