A subdomain is a second website, with its own unique content, but there is no new domain name. Instead, you use an existing domain name and change the www to another name. The subdomain name looks like forums.domain.com, help.domain.com, help2.domain.com (assuming you already host domain.com).
To create a subdomain, please do the following:
Login to cPanel and click Subdomains.
In the drop-down, choose the domain.
In the box before the domain, type the subdomain name you want.
Click inside the "Document Root" box and it will auto-fill.
Hit the Create button.
To delete a subdomain, please do the following:
Login to cPanel and click Subdomains.
At the bottom, under Actions, click Remove.
