Is anybody aware of an application that allows you to view a list of installed Mii's and will let you delete them? I've got assloads of Mii's on my console, partly due to letting every man and his dog create a Mii, letting a 5 year old loose on it and having the Mii Plaza thing enabled... The net result is that my Wii has enough Mii's to re-populate China and deleting Mii's via the Mii Channel is a slow, painful process.
If anybody can think of a way or if any developers feel like a challenge (I hoped LibMii would make it easier but it looks like it can only read Mii data), post away...
... I can't be the only person with a seriously overcrowded Wii!
