I need a commenter like the codeguru/codeproject articles' one ( http://www.codeguru.com http://www.codeproject.com ) : user should be able to post a comment about the article i wrote. I didn't find any easy-to-use tool like bravenet's ones. Guestbook can't be a solution to my problem, because only one gb is allowed to each user. So, what about a commenter?
