The HUB is powered by the Get Satisfaction platform, and as such, new features and functionality become available to us from time to time. The latest addition is that of Points and Badges for users. This "gamification" system hopefully will help persuade users to be more active in the community.
If you're interested in learning more, please take a moment to read over the description of this new feature at the link above.
I also must point out that this is a beta feature that we have requested to be an early adopter of. If you uncover something that you perceive as a bug, or if you have questions, you may comment here or directly to GetSatisfaction. More information about the beta.
Thanks to each of you for your contributions to our site. We're always looking for new ways to grow - hopefully this addition has a positive impact! Feel free to share your feedback below.
