Hide 'Register' button and change the logo?

Thanks Anton for the prompt feedback !, I am a beginner, sorry for my question, I leave here my satisfaction for the excellent project.
But I will keep trying here with the information posted above. Thanks again.

Is there a default login and password to log in as an administrator on the server? there are items in my installation that are not enabled, is that it?

Yes, default login is "admin" for email and password.

Thank so much! :D
