Shit happens. Sometimes, it happens to you. If it does happen, you might wish
there was something you had told the people around you. How you feel, what you regret, where the
money is stashed.
For this, you need a dead man's switch.
This is how this works. You write a few e-mails, and choose the recipients. These emails are encrypted with military-grade algorithms, so you can be sure that no-one except the intended recipient will ever read them. Your switch will email you every so often, asking you to show that you are fine by clicking a link. If something were to... happen... to you, your switch would then send the emails you wrote to the recipients you specified. Sort of an "electronic will", one could say.
The emails are sent in configurable intervals. If you don't answer the first, you will get a second and a third one. If you don't answer those either, your switch will be activated. Of course, you can have your switch postpone its activation (if, for example, you'll be away for some time) by telling it to not try to contact you for a specified period of time.
But nothing. That's it. Nothing to it. The service is provided for free, and you can get started right now. Just log in with your OpenID or create a new account using the "log in" link above.
