How do private leagues work?

When a league is created, it is made either public or private. Private means that members can be added only by knowing that the league exists. This is done via two methods: 1. A unique league code. All leagues have a unique code. If you want someone to join your private league, you must tell them this code. When they access Join a League, they will enter this code into the private code field. 2. After you have joined a private league, you can Invite friends directly into your league. This will send them an email containing a link that will allow them entry directly into your league.
