Personally, I think putting the magazines on a private tracker would probably be the most ideal way to do torrenting. I got approximately 30-40 GB of magazines scanned by Retromags from Underground Gamer, though it was in a largely disorganized and random collection compiled about two years ago. The fact that I was able to get everything I wanted (ie 16 bit era magazines) shows the ability to have continuous seeders on that website. I was seeding the Gamepro 1993 collection torrent there, and had about 5 people get it off me. Because that website requires people to have a good ratio, it is far more ideal than a public tracker where you have far more leechers than seeders.
I personally want complete sets of magazines through the 16 bit era, because sometimes the most important information for my SNES research comes in the more obscure magazines (ie look at the info I found about the Canadian StarFox competition, which I found in an issue of Game Players). Trying to go through and collect it by doing individual web links is tedious, a drain on the bandwidth of this website, and I currently don't have the ability to do it.
