Changed Settings

I have a lot of people saying that they cannot leave messages on my blog. I was not aware of the the fact that I could change settings so that anyone could leave a message. Any of you out there that have had a problem I believe I fixed it. Please if you want to say something do so. I don't care if it was on my first post. I would love to read your thoughts! Thank you so much for taking the time to read what I have to say. Laura
