Q & A
Q: Is every letter and message dropped into Locker 666 sent to my inbox?
A: No. The important and fun majority of letters and messages do get sent but not every one. Otherwise your inbox will get blown to ghastly pieces.
Q: Will I still see previous letters and messages if I signed up late?
A: Yes. You can read previous letters and messages through the archive before new letters get sent to your inbox.
