Never finished it. (Did I publish it on npm? Oops?)
Since then there has been a few gamification plugins built, for example by @nicolas
This is a simple plugin that provides a list of active users on GameVox.
GameVox already has a very sexy embedded control you can add to the forum with an iframe, but it loads slow and takes up way too much space when all most people want to know is who's online.
Feedback is appreciated.
Such great toy could be beneficial to your forum, but may be quite slow in China.
