Just one more step before you're on the list.
You must verify your email address. It's simple:
Check your email now for a message from firstname.lastname@example.org with the subject "Action required: please confirm your subscription." (It may take a few minutes to arrive).
NOTE FOR GMAIL USERS: If you don't see the email in your inbox, check your spam folder, "Updates" tab or your "Promotions" tab and slide the email into your inbox so that won't happen again.
Open the email and click the "Confirm your subscription" button.
Do it now before you forget!
