Bluebird, you'll need to go into the "My Friend Codes" page and click on edit up in the "My wifi Games and Settings" section. There you scroll down to the 3DS games and add your same FC into the 2nd slot. That way you can see my 2nd code back in the "My Friend Codes" page if you click on your 2nd code listed. Enter my 2nd code into your DS.You can only visit my 2nd DS code listed.
I will go ahead and open and when you get that done, just feel free to come on over.
