Ben Hammersley,
Full info can be found at Ben's site, here.
Important info to know: he's looking for anyone who wants to contribute a cool trick, technique, hack, or nifty thing for LiveJournal to the book. There's no money, but you'll get full credit, and your name, URL, and a little bio at the end of the book. Fame and Glory! They'll also be doing exclusive "Contributor" badges for those that participate.
Info is available there to contact Ben directly, and I'll also be making sure he sees this post, since he asked me to make it!
