Thanks to Nintendo Network, we don't need Friend Codes to play Wii U games online or to interact on Miiverse through Wii U, 3DS, or web browsers.
Please use this thread to share Nintendo Network IDs (NNIDs). Remember to protect your private information at all times and follow Nintendo's rules of conduct when interacting on these platforms!
Mine is JonnyNWR. My friend list is currently full (let's hope for the maximum to increase some day), but you can follow me to see Miiverse posts. I will occasionally delete people who haven't been online in a while, or to make room for real life friends, so it doesn't hurt to send an invitation anyway.
