Did you provide an e-mail address when you sign up for the account? If yes, a confirmation e-mail would have been sent to the address. Check the Junk mail folder if you can't find it. Make sure you confirm that e-mail is yours by clicking on the link within the e-mail or copying the link to the address section of the browser and press enter. Congratulation you have successfully activated your account.
Note: be sure to double check to make sure that e-mail was sent from Fido and not someone trying to pretend to be Fido.
