DotNetSlackers is running an XBox 360 Giveway where potential authors have the chance to win one of three XBox 360s. You can learn more by visiting the contest page. Personally, I wouldn't give up this chance to win an XBox 360.
Why is this posted on The Code Wiki tag? Well, I have an upcoming article on The Code Wiki going on DotNetSlackers...i won't be eligible for the prize (since I'm somewhat affiliated with DNS), but it'd be great to see someone else write a Code Wiki article and win an xbox 360.
