I've done it before, but I forgot a key step(s), and I haven't been able to find any resources through Google that help me.

So, imagine a website - www.mysite.com - with the following REMOTE settings in Dreamweaver's Site Definitions:

Access: FTP
FTP Host:
Host Directory: /public_html/
Login: abc
Password: xox

Now imagine you want to create a subdomain - usa.mysite.com. How would you change the above settings to forge a connection for your subdomain? As I recall, Host Directory becomes /public_html/USA. But I forgot the rest of it.
