Start by sending your friend a message! Before you do this, make sure your friend has a scratch account and you know his exact username. When your friend checks it, he will read your messages if he is signed in. Disclaimer: Not a chat room, this is not a immediate chat. You have to wait before the message gets put in the cloud and is ready for your friend to see it. Also, if anyone knows how to do a blacklist, please tell me!
