Since it's not mandatory to provide an e-mail address to sign up for Spaaze, not every account has one, and those accounts which have one have never verified their e-mail address. So whether you can retrieve/reset your username/password really depends on whether you voluntarily entered a valid e-mail address on sign up or not.
To retrieve your username you only need to enter the e-mail address used for sign up. If we find this e-mail address in our database we'll send an e-mail containing the username to that address.
To generate a new temporary password to be able to sign in to an account and set a new password you need to enter both the username and the e-mail address of that account. Only if you've entered an e-mail address on sign up and the e-mail address matches the username entered the password will be reset.
