A personal message (or PM for short) is a message that is sent from one player to another over the Roblox website.
How do I read PMs?
You can read PMs by clicking on the new messages button in the upper left corner of the screen. This will take you to your inbox. From here you can read all messages sent to you.

2. Click send message.
3. Type in the subject (Messages with a good title have a better chance of being read.)
4. Type in your message.
5. Click, send message.
