I just called Juno's customer support, and they said that they couldn't even delete it (some help they are).
They did tell me, however, that if you do not log in to your e-mail account for 60 days it will be considered inactive and will be deleted from their system.

I just called that # and they said: From the account you want to delete, send an email to abuse@support.juno.com. In the Subj line, type "Cancel free membership." In the body, type "Cancel my account for (your email)."
Incidentally, I asked him why they couldn't just post these simple steps on the Juno website. He had no answer....

In order to delete a Juno email account online that is free you will have to have the Juno 5.0 CD-ROM. Ask Juno's customer service to send you a 5.0 CD-ROM. Install it on your computer and download your email account to your computer. Once downloaded, click the Juno icon on your desktop and the opening window will appear. Look to the right on the screen you will see delete or import account. Enter screename and password then click delete account. This will permanently delete the account from your computer and Juno's central computers. If you have a paid Juno account you will have to call Juno's customer service to get it deleted.
