Click on Lyn Smith's wagon picture and then you will see a start conversations button. Then follow the prompts to send Lyn a PM.
When he responds back to you.....you will see that your top button on the top right of the screen the one with your picture of your Chevrolet flags will have a star/dot to let you know you have a message. (It is to the left of the 3 vertical dots).
Click on that and then you will see the word conversations (the 4th item down) and you should see his message there.
