UPDATE: Grooveshark is giving away not just 1 month, but 1 year of Grooveshark Anywhere to each participant in the May campaign. Thanks again.

If you’ve seen the latest version of Grooveshark you know they’re big fans of jQuery and jQuery UI. They want to show their support for jQuery UI and RewardJS by giving away a free year of Grooveshark Anywhere to each person that contributed at least 1 bug fix to jQuery UI during the month of May. Huge thanks!

While we’re here, we want to mention that Grooveshark is looking for awesome JavaScript developers. So, if you’re an awesome JavaScript developer, be sure to visit www.grooveshark.com/careers .

RewardJS kicked off with a bang this week, awarding 4 prizes in as many days – an iPod Shuffle, a Flip Camera, a Nintendo Wii and a Kindle 3G. This is just our first RewardJS campaign, and it’s running for the full month of May. Congratulations and thanks to our first four winners as well as our first full-week sponsor, Bocoup.

$1337 in prizes for fixing just 4 bugs!?

Today only. Check out campaign and rules to see how you could get an Xbox 360 with Kinect and an iPad 2 by fixing as few as 4 bugs in one day!

RewardJS is not a JavaScript library. It’s an incentive program to thank JavaScript developers for contributing to open source libraries, for fun or for profit. To kick things off, in the month of May, you have a chance to earn an iPad 2, a MacBook Air, or an all-expense-paid trip to the next jQuery Conference. And those are just three of the prizes, there’s a different prize every day and every week. There’s no limit to the amount you can win. See the Rules for full details.

How it works

Fix a bug. Get a prize.

• Daily prizes ($50-400 each) to the developer that closes the most bugs each day, Mon-Fri
• Weekly prizes ($750-1250 each) to the developer that closes the most bugs each week, Mon-Sat
• Monthly grand prize ($2000-3000) to the developer that closes the most bugs in the 4-week campaign.

Developers

We’re kicking off RewardJS by running a campaign to see how many jQuery UI bugs we can get fixed in the month of May. Check out the Prizes to see if you find any that are particularly motivational for you. Already have an iPad 2? Don’t let that discourage you – opt for a gift card instead!
