I really like the e-newsletter plugin, and have implemented it on a client's site. My client has additional information though for newsletter subscribers including their physical address and birthday that he will use for marketing. So, two questions...
One, can you add custom fields to newsletter subscribers (address, birthday, etc.), and two, can email subscribers automatically be added as site subscribers/users (though I know this can be done the other way around)?
If the answer to the first question about custom fields is no, it would be important to have the subscribers sync as users so I can use another plugin to add user fields.
Thanks for your help!
