The C3D-L list server
C3D-L is the e-mail discussion group for issues and information relating to the C3D file format. Message to and from the C3D-L list are checked for and any message that contains a virus will be automatically deleted before distribution. Membership is open to anyone. Most companies that distribute or write C3D software are members of the list, as are many C3D users. Message volume is generally low (less than 1 message per week on average). You can contact the list administrator via the info@c3d.org e-mail address.
