How do I subscribe to a player's or organizer's activity?

You subscribe from a player’s or organizer’s profile, then Playbox notifies you about their activity. When you follow a player, you get notified when they join or leave events; when you follow an organizer, you get notified when they create new games. This helps you keep up with the people you regularly play with or the hosts whose games you like, so you can jump in early. You can manage your friends and subscriptions together from the interaction menu on player profiles. You can also subscribe to a venue to hear whenever new games are scheduled there. Unsubscribe at any time from the same profile to stop the notifications.
