Doesn't seem I can, but I wrote my email on my about page in my profile.
I mostly interested on digital files as I'm not a hardcore flight simmer, but have interest in old sims in general and recently I got to play the old dos flight sims.
I find sad that no one thought of archiving the extra and user made content for these games in a public way, as they are discarded as soon as a new one comes out, which make the retroactive perception of the communities that formed around them very shallow. And even though, I did not grow up with these games, I find the unique abstract view of the world they present fascinating.
