Hi there.

You can delete the accounts you created in WHM and start again as follow:

1. First, you have to define hosting packadges, at least one, in your WHM, by allocating disk space and bandwidth to it.

2. Then you create a user account for each domain you need to host, allowing WHM to configure the DNS to those domains.

3. Then, you need to register those domains at a registar, and supply the registar the ip numbers of your newly created accounts, or

4. If it was existing domain names hosted elsewhere, you need to move those domain DNS to your server (WHM) by applying to the registar where they are registered in the same manner as point 3.

Hope this helps, let me know!
