One Customer but multiple different domains?

I had this same question.
You can use aliases cant you?
I am not sure why they called em aliases but they act as multple domains on one user.
When you add an "alias" to a domain it adds a folder to the ftp account and you can then upload the files to it like you want

You can add a second domain when creating the new user(there is a box to checkoff that says "add more domains" or something)

and if you want to after creating the user, you can look up the user and click "add alias" on the left. It will no wbe linked to the main domain of the user. So you login to the ftp as the user, and you will then see a domain2.com folder in there.
