On the left side bar, click "Subscribers Corner" then "Login". Follow the instructions to login and confirm. Once logged in, access "server archives" on the left side bar and locate ACMET in the list of groups. Enter your info in the appropriate boxes and "Join ACMET". Confirm the subscription in the email which follows joining. After that, I think we just wait for confirmation from the list owner that they have allowed us to add to ACMET. Not sure how or when we will be granted access.
