You may or may not have noticed the comments thingy changed. I had been using a comments service so that I could use the Comment Luv thing but it turned out to be more trouble than it was worth. I really liked the Comment Luv too, it was just the JS-Kit service that annoyed me.
I finally figured out that even though I was responding by email to the people that left comments, they weren't getting the email - which is very aggravating. I am not sure exactly how long my emails weren't going through - which is, again, aggravating.
