[Koha] Reports on comments written on opac

Hello, Is there an easy way to see which of our patrons has written comments on items in the OPAC and how many comments they have written? I'd like to see who has done this and who our most active 'reviewers' are. Thanks, -- Hei konā mai, Mark Osborne Deputy Principal, Albany Senior High School.
