Anthony Harradine is tireless in trying to save Australian Maths Ed. He is responsible for MathsCraft and Numerical Acumen, and all manner of things. Anthony invariably takes a positive, Nice Guy approach to all this. Nonetheless, we get along very well.
We have the bigger projects (AC, ITE, SD) in the works, plus an FOI appeal to do, plus 2000 words for a lefty magazine due in a couple weeks. We’re kinda busy. But, we’ll try to keep the general posts ticking along. This one is some fun, plus some history and a couple of puzzles.

Having finally dug, we’ve decided to post the material here, for whomever is interested. Whether or not there will ever be a NotCH 2 is anybody’s guess.
