I have access to WHM and want to create a hosting package for my users with subdomains accossiated with the hosting.
Please help me by telling how can I do that?
In cPanel/WHM, you can simply create an account using a subdomain. Just enter subdomain.example.com (replacing that with the actual subdomain to use) as the "domain" when creating the cPanel account.
You will need a minimum of reseller access to WHM to accomplish this.
