After first activating the plugin, was given a message stating some number of bytes (like 297, I think) had already been sent and errors could occur including statements like headers already sent. If that were to occur, I should de-activate and reactivate the plugin. The plugin did not install on the first try.
Upon the second try, plugin seemed to install and provide an email address, though there was no indication on the Write page of being able to change the address.
Finally, sending an email to the assigned address never showed up on the blogs post list.
