My publisher is preparing to reprint my book _Disappearing Cryptography_. As part of a general maintence scheme, I'm offering a reward of $10.00 for the first person to discover a technical error found in the book. Find as many as you can and win some cash. Naturally, there are some limitations to the offer: * Only the first person to report an error is eligible for the reward. The final decision in the case of a tie, will be up to me. The ties will be broken using the time my SMTP server (access.digex.net) receives the mail. I reserve the right to give out multiple rewards in the case of a tie or a close finish. In fact, I'll aim to do this. I just don't want the situtation to emerge where everyone can send me the same bug report and feel eligible for a reward. * Some multiple errors may only count once. Imagine that the third page was missing from the book. Technically, all following pages would be misnumbered. I reserve the right to group any collection of bugs together and label them one error. I will use this right judiciously to avoid hair splitting arguments, but not to deny people multiple rewards. The more errors that are fixed, the better. * Grammar errors aren't eligible, but I welcome any comments. These disputes are often more issues of taste than rule. -Peter Wayner
