A credit/point system

[Anh Le Giang]

Hi,

I'm in need of a credit system which:

• Users must spend the credit to write the review. This is for preventing fake reviews
• Users can earn the credit/point when his review has high votes
• Users can earn the credits weekly if he login to the site and claim the weekly bonus. This is kind of gamification
• Users can gift others' review which they think it's useful
• User can use the credit to trade for the gift, voucher, rewards, etc.
• There are many more benefits for a credit system like this.

I remember that we have the integration with something like alpha point but I don't see any site applying it and it seems lack of good features.

Thanks,
Anh
