The Highway Forums General Discussion Open Forum Where is everybody?

The "Shoutouts" are the "captions" that you enter when you add yourself to the map, e.g., your comment about you being the one in the middle. To read them, just scroll down a bit and they are near the bottom of the page. Also, see here about adding more Shoutouts:

The Highway Shoutouts

To add a shoutout, just enter your name, zipcode, and shoutout above.
Your name will only appear once on the map, but you can enter multiple shoutouts the same way.

In other words, you go through the same process to add another comment, aka: "Shoutout", as you do when adding yourself to the map; i.e., using the same box and fill in the fields.
