How to register friends
There are two ways to register friends on Wii U, but regardless of which method you choose you'll need to know the Nintendo Network ID of your chum.
Please note: you won’t be able to send requests to anyone who has opted out of receiving them.
To register friends simply follow the steps below:
Method 1 – Registering friends via Miiverse
1) Enter Miiverse via the Wii U Menu or HOME Menu.
2) Select "User Menu".
3) Tap "Search Users".
4) Enter the Nintendo Network ID of your friend then confirm.
5) When your friend's Nintendo Network ID comes up you can see their information by selecting "View Profile".
6) On their profile page, tap "Friend Request" and your request will be sent.
Friend requests sent in this way will show up in the friend list and in the "Received Friend Requests" section of Miiverse Notifications. As soon as your friend accepts your request you’ll appear on each other’s friend lists. Whenever you receive requests you can accept or reject them as you wish – but remember to only accept requests from people that you know!
Method 2 – Registering friends via the friend list
1) Press the HOME Button and then tap "Friend List".
2) Tap "Register Friend" or press the + Button, then enter your friend's Nintendo Network ID and confirm.
3) You can choose to enter a message to be sent along with your friend request.
Please note: If you are younger than 13-years old or your friend has opted not to receive friend requests, your friend will also need to carry out steps 1 and 2 for you to become friends.
