I thought about this:
You know how you have , Sharing, Comments, Forums, Friends, and Special Badges in levels 1-5/6? Well, I was thinking that at the end of each one (Where it says you have to post 50 comments etc.) That there would be a meter to tell you how many you have left to post/share.
Kind of like "Congratulations! You earned the Level 2 Comments badge for commenting 500 times on Kidzworld. (200 Left)"
Nearly every one of us has thought over an idea to the point where it looks impossible to reject, and then we get discouraged. That's not the place to become discouraged.
