I don't think you need a separate log for CITO. You could add a check mark that when checked would add a CITO logo to the cachers log for that particular find. As far as proving that CITO was actually done, well that is just impossible. A lot of the cache areas we have seen would just about clasify as a roadside dump...when you CITO you have no control over what happens when you leave...i.e. tossing trash from a car. Besides we should be doing it because it's right, no to get cudos on the website.
