Can I prove that someone has signed in with double opt in. The user signs up for the newsletter and then receives an email with a confirmation link. Can I prove that.

That’s what I would like to know, too. Over the years there were several users giving me mail adresses which I entered manually setting their status to confirmed manually, too. Now I would like to reset all those people to unconfirmed and want to send them a confirmation mail. How to do?
