Since the featured article by email went silent 6 weeks ago, I've received many emails asking me what happened. I apologize for taking so long to respond. I'll attempt to explain why.
The featured article by email was the brainchild of Kate. It was she who had the idea, set it up, and maintained it. In December, Kate left Wikipedia. After she left, there was no one to maintain it, so it went silent. It came at a bad time for me, as so I have only recently gotten around to fixing the situation.
Not long ago, I began looking for someone to replace Kate. I have found a volunteer, so I believe that you can expect to see the featured-article-by-email return very soon.
Sincerely Yours, Mark Pellegrini Wikipedia Featured Article director http://en.wikipedia.org/wiki/User:Raul654
