On occasion, when in kindly mood, I have silently corrected typos/spelling in the comments at my site.
My new comments system, however, makes the process less silent. “Edited by moderator” shows up in the body.
Let me state categorically to new readers and old that I do not, ever, edit your comments for content. I shall likely have to abandon my editorial practice, however, because the added note is paranoia-inducing.
So you’re on your own henceforward. Let spell-check be your friend.
