If I send an email out to Users, and they click on the footer link to opt out of recieving future email correspondance. How can they opt back in if they later change their mind?
You can make "unsubscribe" field available for editing at aMember CP -> Setup -> Advanced : "User can change the following fields", then it is available at amember/profile.php
I think what Riki is asking is: Many members mistakenly click the unsubscribe link in the footer of the e-mails thinking it is a link to the site and I think she wants to be able to allow them to re add themselves to the e-mail list . I know this is a problem with some of my members, they click it and then do not receive e-mail correspondence, and then they whine when they get no letters, it would be great if they could re add themselves.
