2. Your Flipnote Studio ID will be displayed on the first page of your Settings.

Sudomemo Theatre (Website)

2. Go to your Creator’s Room. There will be a large button to do this if you are logged in.
3. Your Flipnote Studio ID will displayed below your bio (if you have one), inside of the About section.
