Commenting Problems

My mother-in-law notified me today that people might be having trouble commenting on my blog. So, if you're one of those people here's what you have to do until I can figure out what's wrong. I guess when you try to leave a comment an error message pops up and says try again, I guess you just have to enter it again or hit "publish comment" again or whatever and it will go through. I had Chase put my comments on moderation so that I can approve who is commenting. Our family has had problems in the past with weirdos popping in and leaving unwanted comments on our board. So, sorry, I'm new at this, but hope to have it fixed soon.
