Note to Boy, according to my O level maths, is now a third of its way along the journey to publication. Hooray, and thank you to all my supporters! You're a wonderful bunch of heroes. It would be great if we could get it past the 50% landmark, then I could perhaps relax and not keep checking progress every few minutes.

Thanks also for your kind comments about the video. I hope it made you smile. I've been thinking about putting up a short bloopers tape in the future. What do you think? Would that be of interest? You can contact me about this and any other questions on the Q&A section below.

I'll try to answer anything, within reason, as long as it's not 'Where do you get your ideas from?' or 'Should I invest in Bitcoin?'
