Thanks Ricky, that sounds very interesting. I have not done very much with trees and would be delighted to hear more.

Dear GM, if you want, I will send you a copy of the message with your name on it. I do not hack - I lack the knowledge to do so and am not interested in such behaviour. I was not offended at all, but rather happy that the message arrived and very appreciative of its contents. I am truly sorry you see me in such a negative light, but that is not my responsibility, nor my fault. All the best to you.
