Email lists are really discussion groups, similar to what you may have used in groups.yahoo.com or groups.msn.com. When an email is sent to "the list", all members of the list receive the email. Lists are sometimes called Reflectors. There is also an archive of all messages available. The TCRC maintains several lists. An overview of all of the lists are available here Some of the lists are described below.
