Many, many thanks to those who generously spent time scouring the PDF this week to find typos and grammatical errors. The overall sentiment has been "This book looks great! It was lots of fun to read! Now, here are twenty typos I found." Hey, at least you had enough fun reading the book to bother finding those typos!
I have a hardcopy printout of the document, with handwritten notes for consolidating all the edits in one place and each typo-hunter's name written on the front page. Not a super high-tech process, but it works. There was surprisingly little overlap between people's edits, so I'm very confident that the final book will be mostly error-free.
Tonight is the last night to submit any typos and claim a star next to your donor credit. My apologies if I don't reply to you, but a LOT are coming in really fast. I'll do my best to make sure all typo-hunters are accounted for and credited.
