No worries, I can make you a plain copy but the pictures will still be in there. This will allow you to print B&W with little issue but will use a little more ink than my other printer-friendly editions. I'd remove the pictures entirely but this rulebook was written with them in mind as reference for the competition so I don't have a better solution beyond rewriting the whole book itself. Anyway, keep your eye on the page and I can get this uploaded tonight (give me maybe an hour or so).
EDIT - Got to this faster than expected, please redownloaded the zip file and you should find the new BW rulebook :)
