I feel that "constructive suggestions" are best handled through im's. that way no one sees it except the party posting. so called negative comments maybe taken the wrong way when it was not intention of the commenter. it never fails that harmless words can be construed the wrong way. I think that people that are not interested in recieving comments leave the option unchecked. I leave rankings unchecked because after so many comments it is irrevelent. I do appreciate other artists making comments. I feel it is a courstey let people know you did view and a few words never harms anything.   if nothing more than relating to the scene to a personal experience
