hey, i used to use an r4 a lot so i know they can be a pain sometimes. you want to move this to dms if you aren't already getting help with it?
since when did Dms get added to miiverse?
in order to dm, you need to send/accept a friend request on wii u (to be friends on wii u, it's the only way) and then start a dm from the friends tab in your account! ^^ if the R4 is still isn't working, i think i can try to help!
