Copyright Notice

Everything in my pages is copyright by me, and

1. If you use it in a non-profit way you must get permission (I won't refuse; it's a formality) and give credit.
2. If you use it to make money you must get permission (and I'll be reasonable!) and give credit.

It is possible to copyright the expression of an idea, but it is not possible to copyright an idea. For example, the rules of Taxi Chess are the expression of the idea of chess-with-metered-moves, and you cannot cheat the copyright by using those rules and explaining them in different words.

For example, it would be both wrong and illegal to do a commercial or shareware program for Trapdoor Chess without my consent.
