Hello,
I just got a Wii U today and I have a question about linking a NNID between a 3DS and a Wii U. Back when Miiverse was released on 3DS I did not have a Wii U, so I created a new ID on my 3DS. I know it's possible for Wii U users to link and existing ID to their 3DS, but does this process work the other way around too? I mean, if I want to link my 3DS-created ID to my new Wii U, is this possible? I suppose it is, but I just wanted to ask first, just in case.
Thanks!
