Points

The point system was updated with a few tweaks. It seems like the general consensus is that everyone has too many points, and they're able to enter a high number of giveaways without focusing their attention to those of higher interest.

* When a giveaway is setup, all users, excluding the creator, now receive 5% of the gift's value in points. For example, a game valued at $9.99 would give everyone 0.5 points, while a $50 gift would provide everyone with 2.5 points.
* Although your points are rounded in the top navigation, they're now tracked to one decimal place.

We'll test it out for a week, and see how it goes. The goal is to find the perfect balance, that helps to give everyone the best odds to win a game they're excited to play.

points are earned when others and yourself make giveaways.
