I have a book, well, 94 pages, written by a cryppie who worked on the American code machines. I need some proof readers who know HTML to read and mark any problems they find in the book. (Simply marking in red font is all that's needed.) I will tell you one thing about the book at this point, David Kahn is going to write an intro for the online version. Please, only active members of the forum, I won't give this project to someone I don't recognize. (I will consider people who can provide "references". I hope you understand why I have to do that.) PM me if you're interested.
