Argh! Sorry! I've been so incredibly busy that I've only published comments via email for a bit. Nick, I think this sorts out the issue--when I see the actual comments page, I see all your original comments, which I've now published. Oh dear.
I literally have about 90 minutes a day to work, or less, which means I have to get busy with my writing. It's weird I've been able to do all of it pretty much on time so far.
