Open:
	Your information can be requested by anyone who knows the e-mail address of your co-responder.

	Only people who have an e-mail registered with your co-responder may request information files.
	Access can be granted either to individuals, or to every e-mail address within an organisation (eg <all>@adomain.co.uk).
	Addresses can be registered by you using standard co-responder management systems.  If you wish, your customer can register automatically via e-mail or from a web-response form and you will be immediately notified that it has happened.
