I have noticed that certain people seem to be monopolizing most of the categories. Could we set a limit to the number of images an individual can post in each category, say 3 - 5 max. There are individuals who are submitting more than 12! shots per category per week - almost guaranteeing a high score by default. Limiting the # will mandate that they first choose the best of their shots to post and not dilute the pool with lesser quality images.
