      You may have noticed that your Diaspora handle contained spaces, or was different than your login name.
      This was due to a weird error in the early days of Diaspora, and while we fixed the bug,
      there still may have been a problem with your account.  When logging into your account #{user.username},
      your Diaspora handle is now #{person.diaspora_handle}.  Sorry for the confusion!
