Registering a player enables online features for this player. For now, these features are:
- publish score to the online leaderboard
- import/export player (kind of player backup)
Once registered, the player can be unregistered from the device but still exists online.

Note that the player registration is automatically done at the first score publishing.

Unregistering a player dissociates the player on the device from the online registered player. An unregistered player is like a brand new player.

All players are created unregistered.

Once registered, a player can be exported. Exporting a player gives you the online code of this player. This code can then be use to import the player to another device. Exporting/importing is a kind of player backup/restore. With these features you can play with the same player on each of your devices.

We strongly encourage you to export your player code by e-mail (or SMS or whatever) after registering a player.

Player scores on device and player settings are not exported.

Importing a player creates a new registered player automatically associated with the previously exported player. Then, publishing a score, for instance, with the imported player is like publishing a score with the exported player: all points are added to the same player on the online leaderboard. Exporting/importing is a kind of player backup/restore. With these features you can play with the same player on each of your devices.

Exported player scores on device and exported player settings are not imported.
