We have a relaxed policy for commenting…assuming you adhere to the guidelines listed in the Commenters Bill of Rights. It is mostly software driven, designed to keep out spam. If your comment gets caught up in the spam net we will eventually (several hours-one day) approve it. Have patience. If you are absolutely dying to get it in the comments, shoot an e-mail to the address in the sidebar and that will alert us to your presence in limbo.
