I have been trying several commenting system for my Joomla website. Finally I landed using !JoomlaComment from compojoom. I feel this is the best non-commercial commenting system available. Their comment system back-end interface is simple, elegant, intuitive and easy to learn as well.

Another feature that makes !JoomlaComment more reliable is, it supports several anti-spam features like Captcha, AKISMET (my favorite), IP Ban and so on.

Another noteworthy feature of !JoomlaComment is their Forum Support. Daniel and team responds to support queries in a timely manner. Their forum support is top class.

Overall, very good non-commercial comment system. Highly recommended for people looking for opensource solution for commenting system.

Thank you Compojoom for providing us with excellent comment system. Looking for more enhancement to be added to !JoomlaComment component in future as well.
