We are going to play around with giving out NG store credit via some Twitter contests. Basically we'll tweet something and to enter the contest you will need to RT the link. We will then pick a random RT'er to receive the credit. The amount of the credit may vary from contest to contest, depending on how frequently we try this.
To participate you will need a Twitter account and follow our @newgrounds twitter: twitter.com/newgrounds
You will obviously need a valid NG account that we can award the store credit to. I am going to try and hold our first contest this evening.
