You may have noticed the leaderboard and wondered what was going on. The leaderboard represents a new dynamic in online communities. People in the community receive a "point" each time they post a message (or comment) and also every time one of their posts receives a like.
These points will give access to various items in the classroom as well as exclusive opportunities. Check out the leaderboard and you can see exactly what unlocks at each level.
New awards may be added in the future. If someone has already accumulated enough points to unlock the award then they will receive the award as well!
