All boxes development has moved to the GitHub social coding platform:
The planned functionality has long been implemented, and it is very stable. Development has thus slowed down and concentrates on maintenance and contributor-supplied changes.
Code changes must be introduced by creating pull requests on GitHub. Ideas for new box designs should be submitted via GitHub, but since the most beautiful designs sometimes come from non-technical people, I also accept emails for those.
The author can be contacted via email anytime, but please do not be offended when the response is slow. Even if it takes weeks ore months, your email is never lost!
