FarmVille Valentines Mailbox: Everything you need to know

In a late night update this evening, Zynga has launched the Valentines Mailbox in FarmVille. As we've been speculating for some time now, this mailbox functions in much the same way as the Mailbox from last year, in that you'll be able to collect various Valentine-themed collectible objects with the help of your friends, with these items being redeemable for prizes in the game.
