You need a death card.
'Hello. If you are reading this, I am probably dead. Fuck! Anyway, I was a member of an internet community located at
www.nubblies.net. Since I am dead and can no longer post there, would you please ensure that they are notified of my death so that I may be mourned amongst friends? The members of the forum will likely request confirmation of my death, either through a demand for pictures or even a link to a news site. Thank you for performing this grisly task.'
