Here you can find all the information you want about your users.
The status of a player can be email, admin or active. With email the user needs to complete his registration by visiting the link in his registration email. If you as an admin or user with usermanagement permission want to confirm the registration without the user having to validate their email address (or because your webhosting plan has no mail capabilities), simply click on email to grant permission to log in anyway.
With admin the registration was completed and needs an activation by an admin. After activation don't forget to give the new user his permissions.
In any case users will receive an email confirming that their account is "active" as soon as you activate their account here.
