This brought to memory a service I recall reading about that provided assistance in managing your social networks in the case of your death. The service would email you once a month and if you don't respond, it would send you a series of other types of notifications. When you finally don't respond to any of them, it assumes you are dead. In this instance it can forward passwords to loved ones etc that you have designated receive them. It will also send final emails to people. i.e. I've always regretted not telling you that I'm your father....

Interesting times we are living and dying in.

edit: just kept reading and got to the part where they talk about what was once called youdeparted.com. Sorry about that. Shouldn't get too zealous to comment prior to reading in full.
