Added the Windmills project to ModDB. This campaign requires a recent version of FreeSpace Open, which you can download from Scp.indiegames.us - 3.6.10 or above should work fine.
If you have any issues, don't hesitate to bring them to my attention. Windmills has been thoroughly tested and should be bug-free, but due to its experimental nature it is very possible there are still kinks in the campaign that remain unresolved.
