With Windows 8 getting ever closer to its release date, Microsoft today announced that it is looking for volunteers to join its invite-only feedback program for active Windows 7 and Windows 8 Consumer Preview users in the U.S. In return for providing feedback to Microsoft - both by sending the company data or by filling out surveys - participants who stay in the program for more than four months will be eligible for "free software and Xbox games such as Microsoft Office 2012, Kinect Disneyland, and Forza Motorsport 4."
