Badges
I just got a new badge (green P), so I assume I m advanced a bit. (From red p plates to green ones) But I suggest to maybe put all the badges and their meaning up together for members to easily find (and — given human competitive nature — strive to get another one) Then chose the monthly "winner" who earned the most points/badges etc... to make it fun and give people the impression they have achieved something. Just an idea....
