I would be very interested in the same thing. Would it be possible to use this feature for more than just 1 page/topic/category.
MattyRob – nothing has changed within the past few weeks. I have entered my email address many times to test and on 2 different networks where we have WordPress installed. The only message posted on the screen I received said please login to manage your subscription setup. We have two different versions of WP — 3.0 and 3.1.2. Users are still able to add subscribers on the backend but we really need to be able to allow users to subscribe from the frontend. We’ll continue to search/troubleshoot to find out what has gone wrong.
