Granite system creates username when a new member signs in for the first time. It could be your email address or mixed letters from your first and last name. If you're not sure what is your username it's easy to check it out by requesting a new password.
So in the front page click ”Forgot your password?” -button, set your e-mail address and then our system will send you a link where you are able to set your new password and on the left side of the page you’ll see your username.
