This is a great idea, I can pitch in what I got.
I got all floppies in ADF also I got 89 of the 136 magazines scanned and saved in PDF.
I also got some supplement issues and subscribers newsletters scanned and saved in PDF.
I got the following Amiga Format issues:
1-3, 12, 17-21, 23, 26-27, 29-38, 40-63, 65-85, 87-94, 97-98, 102, 105, 108, 120, 136.
So I am missing 47 issues I would love to have.
