I've had a lot of trouble with this plug-in and I've come back to it many times and tried many versions of it. I've had to remove it and reinstall it several times on several websites before I ever got it to a workable state. It's been quite a taxing journey for me but at the end of the day I must say I'm extremely happy with the results. This newest version has an even more user friendly back end and delivers what it promises - and IMO it's the best comment solution out there for Joomla. If you do end up in a pickle - stick to it - when you do finally get it set and done you'll have a top notch solution for your commenting needs.
