How to email individual content to email field? I have a content type that contains information about people, if these people want this information forwarded to them, I'd like to be able to capture an email in an email field and send the published content to them in an email.

I've been hunting around for a way to do this but can't find anything. Is there a way to do this?
If you're looking for existing module to base a solution on. The Print module has a Send by email submodule that supplies a form (/printmail/node/NID) that you can tweak for sending out emails and capturing the supplied emails.

/**
 * Implements hook_form_print_mail_form_alter().
 */
function MYMODULE_form_print_mail_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  // Add a custom submission handler for your functionality.
  $form['#submit'][] = 'MYMODULE_form_print_mail_form_submit';
}

function MYMODULE_form_print_mail_form_submit($form, &amp;$form_state) {
  // @TODO: process $form_state['values']['txt_to']['addrs'] for email addresses to store.
  // Use $form_state['values']['path'] to the load relevant node &amp; save data to its fields.
}
