Hello, and first of welcome to the site.

The hosting costs when it comes to the magazines themselves is taken care of as we have a "lifelong" premium account with file sonic now. So we won't have to keep paying a yearly fee anymore.
As for the magazines you are offering to donate, I do have to say that I have a huuuuge backlog already, so I can't promise to start working on them right away. And as you might have noticed, I take a bit too long on individual magazines to get the digital versions just right, up to a point where it's impossible for me to finish a single issue on a weekly basis.
That being said though, high quality copies of NMS certainly are welcome as they could use a re-scanning and restoration.
As for the Super Play issues, I do have the full set myself.
But having a duplicate set of magazine always comes in handy sooner or later due to unforeseen damage or missing sections that I might not know about.
Just like I'll be looking for a new copy of N64 Magazine issue 8 as I just now noticed it has a part cut out of the magazine.

A secondary copy of issue 7 might need to searched for as well due to quite a bit of damage inside.
