Why so slow to accumulate points?

What's with these points?

The point system is designed to prevent users from entering for every single giveaway. This lowers the overall number of entries, and provides everyone with better odds of winning games they're interested in playing. New users start out with 25P. Every time anyone submits a game, every member of the site gets 10 percent of that gifts value (in USD) in points. For example, if a $50 gift is created, every user on the site receives 5 points. And, if a $20 gift is created, everyone would receive 2 points. These points can then be spent on entering giveaways, or creating invites for your friends.

0.5P = $1 - When entering a giveaway, 0.5P is equal to $1. If you're entering for a chance to win a game valued at $20, you'll spend 20 points. If at anytime you decide to remove your entry while the giveaway is open, those points will be returned.

The maximum number of points that can be banked is 300. This is to prevent users from stocking up on points while being away for long periods of time.

Essentially, since the Dirt 3 giveaways have died down, there's far fewer giveaways being made and so fewer points.

Make your own giveaways, increase the point levels!
