The NTP BOOK is a fantastic resource. Thank you for all the work in producing and collating the content. I understand you may wish to control how the material is shared/distributed however it would be extremely useful if it could be simply printed as a whole. IE as a PDF. Printing each individual article is not really practical. I would love to be able to work through the learning plan as a workbook and have it on hand to refer to regularly when I am looking to improve particular skills. (maybe you could sell it?)
