I'm having a difficult time leaving comments on some of your blogs. I notice that the blogs that have the option of comments being embedded below the post are the ones that won't let me leave a comment.
I'm not sure why that is but if you are on my sidebar and my followers list and I haven't left a comment in awhile, it's because it isn't taking them. I've tried leaving messages on several blogs and then see that the comments never show up.
Just wanted to give you a heads up!
