A while ago I made a little post about Ribbon Hero, a game for Microsoft Office to discover new features and functionalities within the Ribbon.
Today I was surprised with a nice popup when opening Word 2007 (I know I should test Office 2010 :o) :
Go update your Ribbon Hero! It was already downloaded 67,764 times!
Please be so kind to give the team feedback, because it’s just a prototype 😉 .
