I am currently using JComments and am looking to buy a modern and supported commenting extension. JComments has a module at http://www.joomlatune.com/jcomments-modules.html#mod_jcomments_top_posters called "JComments Top Posters" and it's described as "This module displays the list of most active commenters (by number of comments, by the aggregate comment votes)." I use it to list the top commenters over the last 30 days and showing the commenter's names and numbers of comments. The most prolific comments are at the top of the list and the least prolific commenters are at the bottom.
Is this something you can add to CComment, please?
