I really like the front end of it - it's clean and simple. However, needs language selection or just custom field names - that would save time editing the language files. the "force email entry" isn't working - regardless what I selected, it was still demanding to enter email address on the front end. When trying to delete one or all comments at the back end, it didn't delete them even if I was noted that the comment/s was deleted successfully. The last thing I don't understand is when you submit (or attempting to) a comment for about half of second it takes you to the top of the article where notifications are shown and then straight back to comment box (why notifications are not shown somewhere around the comment box?).
Despite that, it is a really good extension and I'm really happy I found it. It's exactly what I was looking for and if you are looking clean lightweight article commenting plugin - it's really great. And despite all the bugs that I experienced I still use it, only gonna wait for the update.
