Easy.  Just remember you have to be Friends with someone in order to send them a message. 

You can send messages to your friends from many places inside the Knockdown Outdoors app.  You can send a message to a single person, or to a group.  

1. Select In-Stand Chat from the main menu. 

This will bring up a list of all your active conversations.  

2. Press the + button at the bottom of the page.  

This will start a new conversation.  Click into the "To" field and add your desired friend(s). Then type your message in the "Enter Message" section and press the "Send" button.

(If you are added to a group message that has people in it that are not your friends, they will show up as "Knockdown User.")
