To respond on your own website, enter the URL of your response which should contain a link to this post’s permalink URL. Your response will then appear (possibly after moderation) on this page. Want to update or remove your response? Update or delete your post and re-enter your post’s URL again.
If there’s the ability to hook into whether or not comments are moderated, one could simplify it slightly with an if/then statement based on the site’s moderation policy to either include, or not, the part about moderation.
