I'm a guest Greasemonkey hacker
A lovely copy of Mark Pilgrim's GreaseMonkey Hacks from O'Reilly just showed up on my doorstep.
I'd gotten a request from Mark to use my Magic Microformat Forms hack from this past summer. So lo and behold, a much-improved version of my code appears in Chapter 4 as Hack #39! Mark did all the work to update the script and prepare it for the book, and I get a complimentary copy—hooray!
