Microsoft sends word of an add-in for Word, PowerPoint, and Excel 2007 and 2010 called Ribbon Hero that is designed to help you boost your Office skills and knowledge. Play games ("challenges"), score points, and compete with your friends while becoming more productive.

Today Microsoft Office Labs released Ribbon Hero, a free add-in that works with Office 2007 and with Office 2010 beta. This is a new prototype that combines gaming and learning to help people understand how they currently use Office, then challenges their Office skills by exposing them to features they may not be aware of – features that allow them to get their work done faster. 

Once installed, Ribbon Hero awards points based on use of features and through challenges that people play right in Word, Excel and PowerPoint. Start earning points by using basic commands (such as bold and italic), and earn more as you use more complex features or combinations of features.    

In addition to this, it even lets people challenge their friends and earn bragging rights. Ribbon Hero connects to Facebook and allows people to post scores, compare with others and more to have an Office challenge of their own.
