This project offers email discussion lists (i.e. mailing lists, discussion groups, email lists, lists) to help parents collaborate.
These discussion lists are archived and the archives are publicly accessible on the Web. Subscribers receive messages sent to the list, and can post to the list unmoderated. Non-subscriber messages may be posted to the list after moderator approval.
