The following mailing lists are both publicly available and provide web-based archives:

• MITgcm-support@mitgcm.org is our "catch-all" list. Please subscribe to send any and all questions about the model and documentation to this address.
  
  
• MITgcm-cvs@mitgcm.org is a "tracking" list meant mostly as a convenience for MITgcm developers. Posts to this list are automatically generated by commits to our CVS repository.
