I am using an external subscription form in an article on our website. We have around 50 lists and so this external form works well allowing people to subscribe to many lists at once.
What would really be cool is to have an external unsubscribe form that would allow people to enter their email address, click a button, and then see their subscriptions. Similar to the unsubscribe page generated by the manage subscription link in an email, but instead of coming from an email, it comes from them entering their email address into a field.
We don't allow registered users on this site.
Might this be possible? How might I go about this?
Thanks in advance!
