I've finally figured out how to upload to git. I've made a repository on notabug.io to share the code that the server uses to run the game.
You can view it here: https://www.notabug.org/FreeGamers
There is also a link to this page in the header bar of our forum.
Any developers or players that want to work together to make the game are welcome to discuss changes, make commits, and collaborate on the game.
