The official Pokémon fan club has reinforced the "Friend Rescue" password bulletin board and "Friend Rescue bulletin board at the official Pokémon fan club" of Pokémon Mystery Dungeon for "Explorers of Time and Explorers of Darkness"!
You and your friends from all over can rescue each other not only with Wi-Fi connection but by using passwords.

This bulletin board has various functions including a mail box that shows your current rescue status and a filter for searching rescue jobs according to various conditions.  It is extremely user-friendly for Pokémon Mystery Dungeon fans as well as for first-time users.
It also has special exclusive features of the official Pokémon fan club such as ranking.  You can enjoy an excitement a bit different from normal rescues.
