• I'll feel sorry for the world when you're no longer around to produce such content.

• I wanted you to know that, you have a fantastic program. Every serious potter should use it. And it would be a good starting curriculum for high school and college to learn from. Thanks for, I would imagine, many hours in developing time. Kudos sir. I hope, by God's good will that I will be able to enjoy it for any years to come.

• In the 4 decades or so of my academic career (I taught ceramics as a major of the Fine Art degree at the University of Kwa-Zulu-Natal, South Africa), glaze chemistry was one of my favourite subjects, though it was too 'scientific' for most students! Your Insight-Live programme is really super! Thanks once again for all you are doing to keep the discipline alive and kicking.

• I write to appreciate your good works by way of the articles you made available on the net .. Thanks a million for your good work. From Nigeria.

• I love your software and I really appreciate you being there when I need help. Keep on being amazing. I am still enjoying insight every day. You were right - having it in the cloud is a huge advantage.
