How to put the htdocs by default

[erastus]

When I create a new account. this new account is by default in the htdocs. where I change that configuration.
for example, if you enter the public ip in the browser, the page of the new account is displayed, and if I add a suspension to the service, go to the directory of the new account. / home / USERNAME / public_html / suspend. as restablesco to the directory being the default
Thank you!
