Great extension. Thanks you. Comments is a much needed feature which joomla is lacking by default.
I have some suggestions on some feature to add to it to make it even greater:
- ratings (multiple parammeter ratings would be even better) when you post comment
- rate this comment for each comment
- Some better way to manage existing comments. Filter comments per status(aproved, pending ...), per user, per category, section. Backend Ajax would be great.
That would be it for now. I'll play with it more.

Thanks for the extension. Exactly what I was looking for. Works well with SH404SEF. Joomla needs it. Keep doing the good work.
