While this country dwells on Football and War, let's take a moment to ponder a service that attempts to send telegrams in the afterlife. Either the most visionary or novel scam, they do back up their service with no guarantees, other than their terminally ill messenger will do their best. Even more intriguing - their FAQ reads as a surreal primer for the afterlife, their advice for their messengers even more surreal: Make contact with the first intelligent person you find and request advice as how best to complete your task. By "person" we mean not only people such as you, who once lived on earth as humans, but anyone else who might be helpful. There might be other entities, such as angels, spirits, demigods or fairies, that are indigenous to the afterlife and who might be willing to help you. Animals, such as dogs, dolphins, apes, etc... might be inclined to help as well.
The agnostic in me finds the realm of possibility fascinating - but I don't think I'd want to entrust my afterlife messages to anything lower on the food chain. I'm sure there's alot of karmic resentment and thus, it would be pretty awkward.
