Double Optin Confirmation For Subscribe By Email

This plugin seems great, tested it a bit. The main thing I noticed (or missed) is that there is not a double opt-in for new email subscribers that are public.

Unless I missed this feature, it would be cool to have a double opt-in email sent first with a confirmation link, then once that is clicked, then the subscriber is added and will get the new post notification emails.

This is a really cool plugin and I think this would make it even cooler!
