The Ptolemy mailing lists are run by http://lists.eecs.berkeley.edu.
This moderated mailing list is for Ptolemy announcements only. You cannot post to this group. The amount of mail here is kept very light (a few messages a year). To subscribe to the ptolemy-interest mailing list, go to https://lists.eecs.berkeley.edu/sympa/subscribe/ptolemy-interest. All mail to ptolemy-interest also goes to ptolemy-hackers, so if you subscribe to ptolemy-hackers, there is no need to subscribe to ptolemy-interest too.
This is a discussion list for Ptolemy questions, bug reports, and to share Ptolemy additions and applications. Since this is a discussion group, mail volume can sometimes be heavy. To subscribe to the ptolemy-hackers mailing list, go to https://lists.eecs.berkeley.edu/sympa/subscribe/ptolemy-hackers. your message. You can search this mailing list for previously posted messages on any topic.
Just like the ptolemy-hackers mailing list, the comp.soft-sys.ptolemy newsgroup is a forum of the discussion of Ptolemy questions, bug reports, additions, and applications. It is best to post to the ptolemy-hackers mailing list instead of the comp.soft-sys.ptolemy newsgroup as ptolemy-hackers goes directly to the mailboxes of the Ptolemy developers. We make every effort to keep up with the compo.soft-sys.ptolemy newsgroup and repost questions from the newsgroup to the mailing list.
The easiest way to read comp.soft-sys.ptolemy is via Google Groups.
