Future Publishing are very aggressive about their IP appearing for download/sale on the internet so you will have a long wait 
To be fair to them, as they explained it to me, the issue is not that they don't want to allow the various Format or other Future owned Amiga related publication issues to be made available but the freelance contributions in ST or Amiga Format to which they only had permission to produce once...in the actual magazine at the time of printing, therefore they don't have the authority to allow someone else's copyrighted works to be distributed in any form and so will never give their blessing for such projects.
I had considered doing AF but the situation with Future is not a big incentive to be honest....especially not the ham fisted charge matrix ebay now applies to people who want to sell magazines on ebay with their ridiculous min postal charge fees enforced, making acquiring the missing issues quite laborious and expensive.
(nobody can sell bulk lots of mags like in the past now as the max postal charge is something stupid like 2 bucks and their fees are so pathetic selling them one by one isn't worth the effort for most I guess...idiot ebay lol)
How come other Amiga magazines published by companies other than Future Publishing are available then? Is it because the companies who published them have gone bust, or for some other reason? I've never heard this excuse about freelance contributors before!
