"Recruit a friend" code thread - New player exp boosts!

[Antonio_Xul]

Here are some new codes for use with the same free items as everyone mentions:

3ZJK6PJN
QJ3YGKPN

A quick question. How can you tell if your code has been used? I've posted a code a while back and the only way I knew it was used is when I received the bonus items up to the Draught Chocobo months later. Is there another way of knowing?

Code in quote still up for grabs.
