If you are a developer, please build MegaGlest on your own and get in touch to contribute (or post your patches on the forums).
We deleted Glest 1.2.0 because of a bug that made the game crash randomly during load. We will upload 1.2.1 in a week.
Demanding information from free software developers is considered rude behavior. Just think about that: The authors are doing all the work voluntarily.
