I made a new web page http://jmonkeyengine.org/
Not as complete as the one before, but I did what I could in a limited time.
It’s all hosted and powered by github so it should never get down. We are looking to have a more permanent wiki on github too.
The web page project is here : https://github.com/jMonkeyEngine/jmonkeyengine-ghpage/tree/gh-pages
Feel free to PR, and enhance it, I’ll gladly accept and merge them.
