When Jerald Spangenberg collapsed and died in the middle of a quest in an online game, his daughter embarked on a quest of her own: to let her father’s gaming friends know that he hadn’t just decided to desert them. It wasn’t easy, because she didn’t have her father’s “World of Warcraft” password and the game’s publisher couldn’t help her. Eventually, Melissa Allen Spangenberg reached her father’s friends by asking around online for the “guild” he belonged to. One of them, Chuck Pagoria in Morgantown, Ky., heard about Spangenberg’s death three weeks later.
