So I got this from Mary:
I tried to comment on the blog. It seemed to demand a registration, which I quit after it seemed to imply I was signing up for my own blog. Clicked on something that I thought might work without the sign-up, but I didn’t expect it to go. That was a week ago, or so.
I have appealed to the blogger.com people for help on this, and I hope they’ll be able to resolve it. My only reason for using this instead of doing it by hand is that I don’t know how to add the comment feature to my own blog (to be honest, I haven’t even tried to find out). But if the Great Unregistered can’t comment here, then comments don’t work, for my purposes, and there’s no point in staying.
We’ll see what develops.
