Alright, before you all go off the walls with this release of Atmosphere (I'm also pretty excited) let me bring you down back to reality for a second to remind you of two things.
1. EmuMMC is still in beta testing. It's highly advised that inexperienced users wait until Atmosphere 0.9.1 to try out the feature.
2. You are NOT invincible to bans. Don't expect to be able to go online with """backups""" and get away with it. You'll still get banned and you'll look like an idiot.
Just wait and don't do anything stupid. If you can do these two things then you'll be fine.
