Check out the announcement of the new XNA Creators Club Web Site on the XNA team blog.
The creators club web site has a new look and feel with several improvements. One of the coolest new features for premium members is the enabling of Community Game Publishing to Xbox Live. Sweet! Games can be submitted for peer review and, upon approval, be published to Xbox Live. You can also check out Dax Hawkin's post on Gamasutra for more details on the process.
