It took a long time to get an email back for me too. Check spam/trash. If you used your email and not your parent's, it might have some sort of age-lock on it, which will keep you from getting the activation code emailed to you. If there is an age-lock, the email will be blocked if it wasn't deleted. How long you have to wait will vary if more people joined when the registration opened.
Also, please try not to post another problem on this thread, start a new one floof. The 'Not getting an email' thing should belong in the Forum + Site Help area, not the Game Help.
Did I get this right? xD
