I uploaded a first version of the Cal3D User's Guide. It still needs some more work, but I think it is ready for a first peer review. Take a look at http://cal3d.sourceforge.net/docs/guide/index.html
The Cal3D API Reference is still in the works (about 50% done). The current state can be seen at: http://cal3d.sourceforge.net/docs/api/html/index.html
Your feedback is more than welcome. My regular email address is still down, please use firstname.lastname@example.org to contact me. Thanks!
