Ptolemy mailing lists
The Ptolemy mailing lists are run by http://lists.eecs.berkeley.edu.
Ptolemy Interest Mailing list
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.
Ptolemy Hackers Mailing list (search)
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.
Newsgroup: comp.soft-sys.ptolemy
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.
