Our goal is to provide visitors with useful and interesting material, and your comments will be selected for publication on that basis.

  • You must be a registered user in order to post comments. Registration requires a name (which does not need to be your real legal name) and a working e-mail address. In order for us to comply with the Children's Online Privacy Protection Act of 1998, nobody under age 13 may register at
  • Approval of your registration may not be instantaneous. To control spam and abusive comments, we may use a combination of manual and automated methods to check you out before we approve you.

  • Individual authors may choose to allow or disallow comments on their articles. Authors are responsible for reading and selecting comments for publication; some authors prefer to disable comments and not take on this responsibility.
