We love our fans. We love websites. So both of them together is like peanut butter and chocolate or something. 
We have resources for those individuals who would like to create a fan site based on Galactic Civilizations III.
The fan site packet can be downloaded here:

There are images and other resources available there, but I wanted to reach out and ask if there's anything we can do or provide to help you get a site going. If you've already created a site, please let me know so we can take a look, and if you are thinking about creating one, also let me know so I can be of any assistance.
Otherwise, lets use this post as a discussion for any fan site related questions or comments. Thanks!
