when you press the green flag your name will be added to the cloud variable (if you're no already in it) Basically this saves usernames of all the people who played this project If you want to use it in your project just put the green flag sprite in your backpack and put it in your project. You can hide both the variable and list.
Please give me credit Do not use this as a chatroom, they are not permitted. It saves letters as numbers in the name variable.
