On November 7th, Miiverse will shut down and won't be able to be used again.
To the people that have miiverse profiles, all of your posts will be gone. You won't be able to meet your friends on miiverse again. Once the day has come, Miiverse will no longer be used on Wii U, 3DS, PC, and other kind of things that use miiverse. Either way... Miiverse will be gone soon.
R.I.P Miiverse 2012-2017 :"(
