To create an account, simply go to the 'Account' section. A new window will appear. Enter your email here, then a 6 digit code will be sent to you via mail. Enter the code in the field that appears and now you have successfully created an account.
To log into your account you just need to type in your email address, a new code will be sent to you with every log-in, so you don't have to remember a password. This process makes your account much more secure and you don't have to worry about a forgotten password.
