It would be great if these files had license headers. It’s not clear what their licenses or who their authors are because the COPYRIGHT file at the project root only states that licenses are different for JQuery and Ember.
Files missing headers: https://github.com/discourse/discourse/tree/master/app/assets/javascripts
Incomplete COPYRIGHT file (would be cool if just headers were updated): https://github.com/discourse/discourse/blob/master/COPYRIGHT.txt
Thanks!
