All comments are approved by yours truly.
I will approve any comment—even dissenting ones—which is not spam or abusive to myself or other readers/contributors.
Authors with at least one previously-approved comment will not have their comments held for moderation. Those will be published immediately.
Because of the manual approval process, your comment may not appear for several hours. If it seems to be taking forever to appear, please email me at ah at my domain.tld and poke me. I sometimes miss the notification emails.
