Roblox 2010

*It's 2010. You are in your room, playing Happy Wheels on your PC, when you suddenly get an ad for Roblox on the screen and you decide to download it. When downloaded, you open it and the sign-up screen turns on, a very simple and basic layout. There's also the guest option, to play games and have a limited "safe-chat" function. Fill out your username, password, gender, age, birthday. You decide everything for your account or guest, what do you do?*
