Click on the Players tab
Under the player options drop-down select New Player
You will be presented with an empty new registration form which you can complete. Fill out the form and register one player by clicking 'Create and Finish', or click 'Create and New' to keep registering players.
Once finished, click on the player options drop-down again.
