If a coupon is for 1-99% off, then it gets a $10 reward if it wins. If it's for %100 off, then it gets $5 if it wins.
The scoring for the voting contest should have a cut-off after X number of hours, otherwise I think there are a lot of people that wait and vote on the most popular deals for the sake of voting on them. Maybe it would be better if only the first 5 or 10 people that voted for the "best deal of the day" were awarded points.
A member is not rewarded for choosing their deals carefully. Someone that blankets the site with deals is bringing down the quality of the site. Maybe each member should be limited to submitting 5-10 deals a day.
If a member gets more than one of the most popular deals in a day, then the member should be eligible for more than one prize in a day.
Just an FYI note, vinhdanh was double awarded on February 13 thus there is a discrepancy in the score: one of the vinhdanh's daily winners didn't score +5 points.
Maybe, it's just the points. I'm confused about that.
