 This grandma left behind a coded a secret message for her grandkids, and it would take them nearly a decade to decode the cryptic letters and solve the strange mystery. A meta-filter user named Jana Kay lost her grandmother from brain cancer in 1996, but not before she left an intricate series of coded messages behind. During her final weeks, the grandmother filled dozens of index cards with long strings of letters that made no sense. No two index cards matched, and many contained repeating combinations of letters. As soon as Jana posted the cards online, users cracked the code within 14 minutes. One user quickly identified that the letters on the back of the card represented the first letter of each word in a prayer. Building off of this, the forum worked together to decode the front of the card, revealing Jana Kay's grandmother used her final hours to write an extensive personal prayer wishing for the well-being of her family.
