On every login page you can use the 'forgotten password' function to reset your password. To do this, please enter your registered email address and click 'reset'. You'll then receive an email with the subject 'Reset password -- activation link'. This email contains an activation link. When you click on it your password will be reset and you'll automatically receive another email with the subject 'Change password -- step 2 (new password)'. At this stage you'll be asked to enter a new password. From then on you'll be able to log in again using your new password.
