The MMT developers maintain the following mailing lists:
Communication between developers and users as well as among unsers. Announcements about MMT (e.g., new releases) as well as any general requests or inquiries. Typically low traffic.
Communication between developments. More traffic and more technical.
MMT is hosted on github, and users are encouraged to submit git issues for bug reports, feature requests, etc.
