Ziggyware Summer 2009 XNA Article Contest
Ziggyware just launched a contest: Writing a XNA related tutorial for XNA developers.
The prizes are great and you can learn a lot with XNA. Find more information in here.
As you may now the Game Studio 3.1 is already out there available for download, check out what's new here. These new features might be a good starting point to write down a tutorial.
To finish I just wanna share these links with you:
