If you've played SSBB, you'll know that you get a user-submitted screenshot, replay and stage every day you connect to Wi-fi(seems like that's the ONLY part of Brawl's online that actually works). Nintedno are terminating this service from June 30 onwards.
Pretty fine by me, one and a half years of Brawl and everything starts to get a bit stale.
It's just rental stuff, not your own. If you get one a day and they don't self-delete, your Wii will be full of other peoples screenshots and videos(you can't delete them yourself)
