The login and password are sent to the e-mail address provided in the registration form within 5 minutes. If the e-mail with the password did not come to your inbox, check the SPAM folder or the Other / Offers folder.
If it is still not there, you can try to reset your password by clicking Log in > Forgot your password? The link to change the password should come to the e-mail.
If this does not help, write to me from the e-mail address provided in the registration form to firstname.lastname@example.org – I will set the password manually.
