This site http://bit.ly/SYJ3jN uses Aweber to send updates whenever something new is posted.
I need a button at the end of every email that would say "Subscription preference: Switch to weekly dose of inspiration?"
And whenever the subscribers clicks that it should take them on a "change your subscription page" on http://bit.ly/SYJ3jN. On that page there should be a new form that will allow subscribers to "update their subscription". When people signup on this, they should get dropped from the "dailydigest" list and be added to a "weeklydigest" list.
We can talk more on skype if further details are required.
