Is this a print only things or can you purchase a PDF or some other online download version too?
He (Charles Hinshaw, he’s here on the forums y’know 
) provides PDFs as well I believe.
At the moment, it is print-only (there are PDFs and resource files but they aren’t a separate version). In the future, a digital-only version will probably be released as well. After having just cleared up some printing/production problems, this is next on my list of things to tackle.
Talk to Thomas at 3d attack. He has built a pdf system for his magazine. You should ask for advice from him. 
Good luck with your mag!
