The Action Network App gives users the ability to follow friends and have friends follow them.
To allow your friends to follow your bets, you'll need to go into your settings, which can be found by clicking the settings symbol in the upper left corner of the 'My Action' tab. Within settings, click 'Profile', which is where you can change your name, add a profile photo and disable/enable friend following.
Once you are back in settings, you can scroll down and click 'Share With Friends' to send them your personal link.
You can also provide them your username which they can then search from the 'Follow' tab.
