Right now, basically all user-created content - mods, ships, missions - are locked away inside Steam workshop, which isn't great for non-Steam users!
The purpose of this forum is to maintain a list of downloadable mods, ships and missions created by forum users. You can export your creations to files, upload them to a file-sharing site, and link them from here. Create one thread per creation.
I'll create entries for the example mods I created. Let me know what you think of this system. I can also create a more fancy database, but I think this forum may be the simplest way of doing it.
What file-sharing can i use best?
I've worked with a great deal; but as the common browser I appreciate ZippyShare the most. It should be more than enough for A:CTS files.
