JComment allows users to post comments to any content of your website and it integrates with any extension using only its core capabilities.
It can be enabled for any specific extension and view by simply selecting them! By default comments are active for the single article view of the native content component, but JComment can be easily enabled for example for Easyblog post view, K2 article view, Kunena thread view, or whatever extension you have installed on your Joomla website.
