One of the benefits of being a member is the members-only email discussion forum hosted by Yahoo groups, often referred to as the "eList".
Joining is easy, and you do not need to create a Yahoo account. Simply send an email to firstname.lastname@example.org from the address you wish to use to subscribe. You will then receive an automated email asking if you initiated this process and requiring you to click a confirmation link which will lead you to the Yahoo website.
Before submitting the final request for approval, be sure to include your name in the text area so the moderator knows who you are and can verify your membership status before approving the subscription. Once the moderator approves your subscription, you will receive an automated email message on how to post messages and adjust your delivery settings.
SIHR also maintains a second "Brainstorming" eList where members interested in the operation of the society can discuss various topics such as the constitution, voting, awards and more. To join this list, please send an email to email@example.com, which will entail the same process as described above.
