Wait, it works! ...I think... If anybody says anything against Scratch's policy, report them. All messages that are sent will show who it is sent by. You must be a Scratcher to send messages.
Recommended character limit is 128, if you go higher, you will enter a "danger zone," where the message might not send. While your messages are encrypted, they are definitely NOT secure. Also Scratch, if you don’t like this project, please don’t ban me please :(
