Our sites are designed to work with a
single domain name. If you have additional domains, you can set them up
to forward to your existing domain name using URL forwarding. This
service is provided by your domain registrar.
When setting up URL forwarding with your
domain registrar, you should only be asked for which address you want
to forward to. The address to use is the domain name you have already
set up with your site.
For example, if your current domain name attached to your site is abc.com and you have another domain, 123.com, you would forward 123.com to www.abc.com. You would do this with the domain registrar that you bought 123.com through.
NOTE: Links should use the domain name
you've set up in your site's 'Edit Site' -> 'Domain & Email'
menu, not the domain that is forwarding to the site. Using the
forwarded domain in your links may cause them to break.
