Problem Posting Comments?

A couple people have emailed me and said they can't post comments. But, my mother-in-law, Colleen, did so it has to be working. Just go under a post and you will see how many comments have been posted and at what time I posted the blog. Then just click on it. It will then have a box for you to add a comment, then you have to type in the code it tells you, and if you don't have a Gmail account click on anonymous. Let me know if you all are still having problems.
