Previously to the launching of the Ez Comments extension, we needed to implement commenting system through to a custom comment class and configure a pre-publish trigger to enable pre-moderation. The UI for comments managment was ugly and approving or denying multiple comments was a painless task, and unless you were using an extension like power_content you didn't can put the comment form inside the article or post.

Ez Comments comes to improve usability and efficiency by using their own database tables for store comments, subscription information among other things. Now it's included together with Ez Publish 4.3 or above.
