I am running WPMS for a school, and many teachers are requiring their students to make comments on posts that they write. Most, if not all students, are not members of the blog they are writing comments on. I am trying to figure out how to get a list of the students each with the number of comments they have made across all posts next to their name. Then I would like their name to link to a page that displays all of the student's posts. I have tried the recent comments widget code, but that does not display what I am looking for. Any help will be greatly appreciated.
