As of today (July 10, 2005), I have officially declared the OpenMAD project abandoned by myself (although it has for considerably longer been in a state of complete neglect).
The www.openmad.org domain and webspace (which was donated to the project) have expired and become inaccessible to me, respectively. I also no longer receive mail sent to email@example.com.
The sourceforge website at https://sourceforge.net/projects/open-mad/ will remain, and the code which was developed will remain available for download by those still interested.
If you are interested in adopting the project (most likely with the goal of converting it into a general purpose differential game engine), please drop me an email. You can find my contact details on my website.
