            If you already signed up, your registration is taken into account. The BDE must validate your account before
            your can log in. You have to go to the Kfet and pay the registration fee. You must also validate your email
            address by following the link you received. If you forgot to register to the WEI, then you can pre-register
            to the WEI after your account get validated, so please go to the Kfet.
