Michael has written a superb blog post on how to debug Etherpad Lite. If you do need to debug Etherpad, Etherpad lite might be your best option as it has a more simple, easy to understand architecture and now thanks to Michael, better documentation!
We are looking for new talent to get involved with the Etherpad foundation. We have a pretty exciting few months ahead of us as we plan to launch the next evolution of the Etherpad software.
