Hi there! I just came here in order to point out that a lot of links in the tutorials and the wiki are outdated. If someone could fix them, that could be very helpfull for the ones that are learning 
Hello, thanks for the report.
It could help that you tell us which ones though.
Thank you!
For example, in https://jmonkeyengine.github.io/wiki/jme3/beginner/hello_asset.html the “Download_the_town.zip” doesn’t work. It is reported in other part of the guide, too.
And the wiki is full of, I can’t remember where, sorry.
