A list is a place where information, questions and messages are posted by a group of people with a common interest. Every time a message is posted to the list it is automatically sent to everyone on the list via e-mail. It is a wonderful way for you to learn more about your shared interest and for you to pass on anything that you feel is helpful. The list is also a great place to make new friends with people that like the same things that you do.

The lists usually contain archives. The archives are a great place to go through to learn even more.
