Give that man a jar of cookies for that answer.
Thank you for explaining that Jabelar, but i still think, for the good of the whole minecraft modding community, there should be a documentation effort put in place. It would help all modders get the best of Forge and Minecraft... Yes, the work has to be done again on each new supported version but hey, the code can move, but it's not a whole new version each time, some principles stay, some change. So creating a multi-version documentation shouldn't be too hard.
If you think at how much time is put all around the web at people creating countless video tutorials, text tutorials and then all the work put into the forums to help each other, i'm sure it possible to convert a bit of that into a documentation base that can be reused over time.
I actually like documenting a lot, and if there is support from the community, i wouldn't mind putting my efforts into documenting Forge, FML and Minecraft along with directing a small team of dedicated people that want to make this possible.
What would be the best way to launch this initiative in your opinion?
