In your Mighty Network, you have an opportunity to follow other members, Hosts or moderators. When you choose to follow someone, this will trigger more of that person's activity to show up in your feed. You will not see posts from them in Spaces you don't have access to as well. You will also get notified whenever that person posts something new.

To follow someone, just navigate to their profile and tap the button that says "Follow." That's it!

If you ever want to adjust your notifications for members you follow, go to your Profile Photo > Personal Settings > Notifications. From there, you can toggle on or off the option to be notified whenever people you follow add new posts.
