If you have forgotten your password, hover over “My Account” at the top right of the home page and select the link "Forgot your password? Click here". Fill in the email address you provided when registered and select "Send". In the next few minutes, you will receive a confirmation email stating "To change your password, please follow the link below". By selecting the link, you return to the website to fill in a new password and save it.
In case of not receiving the email soon, please make sure you have checked the incoming mail folder, as well as those of Spam/Junk/Trash, for it might have ended up there.
