"Shelly, here's what it says about unsubscribing to the e-mails if you're not a registered user: How do I unsubscribe from comment notification emails? Submitted Jan 19 by Giannii Calvert If you do not have an account, you can click on the unsubscribe link at the bottom of the emails. When posting a comment in the future, make sure the option "Subscribe to all comments" is unchecked if you would not like to receive email notifications for this comment thread. Email notifications are sent per comment thread (blog post or article) that you decide to subscribe to." - Robert Seidman
