I would like to see a class for Art... where nudity is used for the Art it expresses and not just for the pornography in it... I enjoy erotic ART very much... and appreciate the skill and aptitude of those that create it.... But I very much agree that a rating based on comments is the best way. If someone takes the time to comment then it has more meaning than just clicking on a thumnail to see what the image really looks like.... IMHO :)
