Free Cities' source code is now hosted on a GitHub repository. Along with the new, TweeGo-based development environment, this should improve collaboration between contributors.
If you are unfamiliar with Git and are contributing or are interested in contributing, the repository will be of interest primarily as a source for the new development environment. Mods can be submitted directly to me as before.
Active collaborators experienced with Git are welcome to fork the repository and contribute code via pull requests, or to create personal forks of the repository and modify the code to your liking. However, please read and respect FC's very minimal modding policy, and please abide by GitHub's Terms of Service.
