I was thinking under the "stats" tab on each of our ibles where we see "Total Views", "Today Views" etc. They could call them "Favorited" and "Downloaded" and just place them below "Rating". Since the box already grows from the expanding list of referrer websites, I doubt one or two additional lines would be a problem. There's also plenty of room on our profile pages under Instructables. The only stats shown now are "views", "rating" and "comments", so there is enough horizontal space to add additional stats (if they so choose). ;)
