I have been hearing that you guys are unable to leave a comment. In the photo below I have made some notes for you. When you go to the blog, make sure you click the member sign in link below all the members, after you have successfully logged in your user information will be located above the members list. At this time you will be able to make a comment to any post. I did test this out and it did work for me. Let me know if there are any more issues. Click the image for a larger view.
