Only just realised this thread existed! Anyway, here is my 3DS code. I might add my Wii Code as well, but I don't play it as often and I gave away my Mario Kart Wii as a gift!

3DS Code: 5455-9865-9131

I don't actually have any friends on my 3DS, and I've owned it since last Christmas so it would be good to have someone to play with!

Oh, forgot, if you do add me (and thank you if you do!) just send a small visitor message. Just so when I open my 3DS I'm left wondering who the hell this person is!
