Some of you have mentioned that you can't see your comments and they seem to disappear after you write them. Though I changed the comment format from a list to a thread so my responses would be more obvious, that is all I formally changed.
I have always had the blog set up so that I have to approve the comments and post them before they become visible. I do not believe that any comments have actually been lost. Those of you who have added a second comment out of concern, both of your comments are visible at my end.
I will try to look at my blog from someone else's computer to see if anything looks different that suggests why you might be having a problem. Only a few of you have mentioned this so I am assuming not everyone is having trouble leaving comments.
