Are you fed up of remembering your S-user ID like me?
There is a hidden secret which allows you to use a friendly user name instead of S-user ID.
Go
here. Log in with your S-user for one last time :-).
Under 'Personal Information', hit 'Edit'. Provide a new 'Login Name'. What more, you can even provide a space in it. Hit 'Save'.
Now forget your S-user, you can always use your 'Login Name'.
Let me know how it went.
Who in the world allows a space in the user name?
