Look in the "Account details" box on the right side of the site, inside you will find your "level". If your "level" is "authenticated user", this means you have not activated your account yet.
Please go to your mail box (the one you registered to Poker Professor with), enter the mail sent by the site with the subject: "Account details for (your Username) at Poker Professor". Click on the activation link inside the mail, your account will be activated and you will be in "Entry Level".
If you cannot find the "Activation mail" sent by us in your Inbox, please look in the "Spam" box - as some mail clients may confuse it with Spam mail.
If you still cannot find the Activation mail - Contact our support team by mail: support@pokerprofessor.com or through the sites' contact us form.
