You would have to use a $_GET

$refferalemail = $vbulletin->input->clean_gpc('g', 'email', TYPE_STR);

Make a plugin in the register hooks and put the above code in it. Make sure to modify it to your needs.

And in the registration templates (pretty sure its register_rules) find the email input fields and inside the email input fields put value="$refferalemail"

If you want the email link to carry over from the Accecpt Forum Rules page to the registration rules page you will have to modify the "Form Action" in the template register. find (<form action=") and at the end of the link put (&amp;email=$refferalemail)
