I had one problem though: After installing jcomments, it worked fine for a week and one day all my comment username (front end)/e-mails (back end) fields were deleted. I posted on their forum and got reply right away. Next I had pagination issues, and I got quick solution. For a free extension, I did not expected this kind of support. Featurewise this is a great component and with excellent support, I would rate this Excellent. Keep it up !
