Inactive Account Manager is a new feature that makes it easy to tell Google what you want done with your digital assets when you die or can no longer use your account. For example, you can choose to have your data deleted after three, six, nine or 12 months of inactivity. Or you can select trusted contacts to receive data from some or all of the following services: Blogger, Google+ Profiles, Pages and Streams; Picasa Web Albums; Google Voice and YouTube.”]
