Leaving a New Reference
To leave a member a reference, go to their profile screen on the app. Then, depending on your device, tap the 'Settings' button, the 'three vertical dots' icon, or the 'Action' link at the top-right corner of their profile. You can then select "Leave a Reference" from the menu that appears.
Editing a Reference
To edit a reference, you can follow the same steps as above. Your existing reference will be replaced by whatever text you leave in the 'new' reference.
At this time, members are unable to leave a neutral reference or state whether they hosted, surfed with, or traveled with the other member when leaving a reference on the app, but if you would like to you can still do so from the website.
