/Me is easy. It’s just saying a message instead of saying the “[!]” it says your name. Like if you type /me (Your message) it will say this: * (Your name) (Your Message) That’s only in Minecraft Bedrock.
If you want to tell somebody in private, use /msg or /tell. They’re mostly the same. I will explain them next time. Come in 3 – 1 more days to see it.
