Is there a way for the email field that is in the CB Core and in the "Contact Info" tab to appear on the user's profile in the frontend?

Right now, I have to make my own email field (e.g., cb_email).

When the user registers, they need to fill in their email twice. How can I make this so that they only fill out their email once, and this appears on their frontend profile?

I'm also interested in a hack or solution for adding the email given at registration to the Contact Info tab.

I explain a hack to cb.core.php that displays the email under the users name on the main profile view (just above the avatar).
