Commenting System for Joomla
One of the things that Joomla lack in its core is commenting system. To enable comments in Joomla powered website, you need to install external extensions. One of the most popular commenting system is jComments which is now available for Joomla 2.5.
jComments is loaded with many features and you must give it a try if you need a good commenting system. To see how it looks in your website frontend, you can see the commenting on this page. I have installed jComments on this website.
