Official Recruit a Friend Code Thread

Usually you email it to yourself, copy the code, and then paste it for someone else to use, I think.

I did like you said and got this:
HAN3YUE6

Now someone has to use it right ?
I would be really grateful to anyone who does

By the way, only one person can use the code ? If no, then does that mean if 3 players used the code I'll get more feathers ?
