Oh, I see! If you click on the name of the person, you'll be taken to their profile. On the right side of the screen, you should see "send this user a Private Message". Click it and you'll be taken to the PM window with their name already in the To: field. Type up what you want to say, hit send message and you're good. You can also go to your own profile by clicking on your name from the forums and then clicking the PM icon. From the PM window select "New Message" and type the user name of the Community member in the "To" field and off you go.
Interesting. Let’s get this all straightened out for you. When did you place your order in? Can you please send me a private message with your phone number and PIN?
To send a private message just click on the picture of any Boost Mobile agent and, in the next screen, click "send this user a private message".
