Well, I figured since we had a PSN thread and an XBOX Live thread, and I didn't see a Nintendo-related thread(maybe I'm blind? o-o), I may as well make one.
So, post your Wii/3DS Friend Codes here, and your DS game Friend Codes if you so desire.
I personally don't own a Wii, but I have a 3DS. Code is 1805-2947-4305.
And again, if this has already been made and I happened to miss it, well...whoops.
