It is recommended to use email to subscribe to the CCAAW email list. There is less typing because the email address is usually supplied by the email app. A signature may supply most additional information.
Subscribing is not the same as registering for the CCAAW. Registering for the CCAAW automatically adds your name to the email list and subscribing separately is not required; however, subscribing is not sufficient to register you for the CCAAW.
Alternately, one can subscribe by answering questions on a form. There are more questions to answer since nothing is filled in automatically.
