Last week, I offered $10 for the first person to report any technical errors in the first edition of my book, _Digital Cash_. I got many good suggestions for additional topics to add to the book, but not one mention of any errors. So I'm doubling the reward. $20 for the first person to report a technical error to me. The details and restrictions follow this message. I would also like to encourage people to continue to send suggestions. If you thought some topics were covered too lightly, let me know. This isn't a technical error, but I reserve the right to reward you anyways. Also, I hope that any company with new or improved products will write. One of the biggest problems I've found in researching the book is finding the right person to contact in a company. So I encourage you to volunteer. --Peter Wayner (pcw@access.digex.net) 1) The offer may withdrawn at any time. Check my web page for any changes. 2) The offer could be increased at any time, but it probably won't be. So don't push your luck waiting for more money. 3) My decision on the "first" person to send me a technical error is final. I may choose to reward both people if it is clear that they found the error independently. The limitation is necessary to keep people from telling their friend, "You want $20? Just send this email message to this guy." 4) My decision on what constitutes a technical error is also final. Errors in grammar or word choice are not rewarded. But you're free to write about them. It's not that I don't want to hear about them. I just think that the concept of "grammatical error" is so ill-defined that I don't want to get in arguments in that domain.
