If you preordered Elemental using tokens, a registration has already been added to your account, but is not active. This is because we have already deducted the tokens from your balance.
If you preordered Elemental using a credit/debit card, a registration will not be added until the beta comes out. This is because we will not charge your credit/debit card until the beta becomes available.
Regardless of what you used to preorder Elemental, everyone's registrations will become active and valid at the same time. You're all on even ground and will be ready to go when the beta is released.
