The process is really simple, but there are a couple of complicated concepts we need to discuss...like adults please.
There are two ways to add a domain to your account. It can be a Domain Alias (and redirected) or an Addon Domain.
An Alias is effectively a parked domain and figuratively speaking doesn't take up any space. That is why you can have an unlimited number of them. With an alias you can use email. You can also redirect the domain to a completely different domain or you can just let it sit there invisibly until you want to use it.
This is what you would do if you had YourDomain.com and you wanted it redirected to your primary account domain YourDomain.com.au - create an alias with YourDomain.com and then add a redirection.
Addon domains count as part of your hosting package. Each addon domain is counted a website. Basic hosting includes your primary domain. Additional hosting space can be purchased for a very reasonable annual cost.
