Comments now require approval before they appear

Due to an unrelenting attempt by spammers to advise you of the latest athletic shoe deals, or mortgage restructuring deals, or other exciting services, I have changed a setting on this blog so that comments require approval before they appear.  I am doing this solely to keep spammers from being rewarded by whatever "google juice" a link from this blog supplies.  Topical comments will be approved as soon as I can get to them.
