Hey,
Just wondering what people are doing in their games? Are you automatically signing in the player, or do you have a button/prompt?
The checklist says that you should include a button if you have a mixed audience (children under 13 playing the game), but most games I have come into contact with automatically sign the player in.

Button seems a bit clunky to me.
Cheers,
