You can Private Message up-to 6 users in a Private Message thread. To start a PM, follow these steps.
- From the Open Loop or any Closed Loop, tap on +Private Message
- Select the users in the list you want to PM
- Tap Start and type your message
Pro Tip: You can only PM someone who you are connected with in a group. If you are a new user to Loop, you will first have to join groups before you can Private Message someone.
