Question regarding pnid deletion

If I delete my pnid will my save data be wiped?

Also can I reuse the same email for a new pnid?

You can re-use the same email, yes.

However, when referring to PNID and save data, are you referring to Wii U or 3DS?

3DS - a PNID is only used for Miiverse, independent of games.

Wii U - the save data is tied to the user not the PNID itself. However, there is no way to separate a PNID from a User once linked.

You can make a new user and use SaveMii homebrew app to backup/restore save data to the new user, though.

Alright. Also please disregard this message going forward, I had second thoughts

Alright. Want me to close this thread?

Go ahead that’s fine
