JA Coders was a website dedicated to the discussion of coding for Jedi Academy created by Raz0r. It also contains various resources, such as tutorials, to assist coders in learning about the source code of the game and how to add various features.
Various members of the JA Coders community are working on a project called "OpenJK".
The readme of the project states:
The purpose of this project is to maintain and improve the Jedi Academy and Jedi Outcast games, developed by Raven Software. This project does not attempt to rebalance or otherwise modify core gameplay.
