For those who have tried to leave comments over the last month and then wondered why they didn't show up, I believe the mystery is finally solved. Somehow in the transition from the old Blogger interface to the new one, my Settings did not hold.
Comments are moderated to prevent spam, but my email address was not filled in, so Blogger had nowhere to send the moderation notices to. I just figured this out today and fixed it, so please comment on anything that strikes your fancy.
Sorry about that. I am my own worst tech support.
Now go comment on something. Thank you.
