We’re going back to our old comment management system. The new system worked well for me when I tested it, but it caused problems for a significant number of you, so we won’t be using that system. Things should be back to the way they were before we made the switch. If you have any difficulties, please use the Contact page to let us know.
Sorry for the confusion.
Note: We’ve had a Reply button next each comment for a long time. At least I see one in IE8. If you reply to a comment, it is not indented under that comment, but it does appear under that comment and not at the end of the comment list.
