You're the greatest! Thanks Edwin for your dedicated and informative work.

Your web page has been a great inspiration to my design ethos, keep it up!

Wise, timely and uplifting words. Thanks!

You'll be pleased to hear that we've had universally positive feedback from the first SPD workshop, with more people that usual commenting that they found it an enjoyable and stimulating day.

Fabulous. Your website is indeed inspiring. Biothinking is what we all have to do to become more balanced and live in equilibrium with our environment.

For engineering students who need practical methods to come up with better design output, your proposals for quick evaluation of sustainability form a very realistic approach.

Thanks for another great piece. You definitely expand my mind.

Your case studies are wonderful!

Bravo! I intend to let all my students know of your course, which I find to be wonderful thoughtful and friendly, they will love it!

Thanks for the constantly-interesting flow of stuff from the Biothinker!

Your website and newsletters have been an inspiration

Your Story of a Sustainable Day is brilliant

Thanks for your excellent analysis Edwin. It's very helpful.

I think your column is fantastic - amazingly thorough! You obviously spare no effort on behalf of the environment. I feel the same way about it. Wish that there were more such folk on the planet, and fewer of the 'Other' kind! I will gladly spread 'The Biothinker' where'er I can... Take care, (a recent subscriber; sorry, I'm not Swedish!)
