Change Details

Things to consider: * Make this page open to public (but subscribe functionality only for logged-in users). * Don't use radio buttons; most users wouldn't expect that changing a radio button would do something without submission.. we need to figure out something else * Show the user a success message when subscribed. * Increment subscriber count after subscription. * Should only appear for JS users. Non-JS users should be shown a link to Special:Newsletter/id/subscribe.
