An addon domain is a domain name that that points to a subdirectory
within your account. For example, you may want innovation.org.nz
to point to business.org.nz/innovation/. Addon domains
must be registered domain names that you own and configured to point
to your web site's servers.
To add a domain to your web site:
Click on the Addon Domains button on the home
page.
Enter the domain name in the New Addon Domain
field.
Add the directory that the addon domain points to in the Username/directory
name field.
Enter the password for the domain in the Password
field, if required.
