Hi. Your ftp address, for the Nvu Publish FTP would look like this:

ftp://www.t76-ham.com/t76-ham.com

(the domain name is repeated because of the way Dreamhost organizes virtual domains).

Your username and password were chosen by you in the Web Panel (or when you first set up your account).

I don't use WSFTP, but most stand alone FTP programs just need to see your server address: www.t76-ham.com
and username and password.

Once you are connected, you can upload either by selecting "upload to server" -- or some text like that -- and browsing for your files, or dragging and dropping your .html files directly from your desktop to the open FTP window (Dreamhost's server, where your published pages go).

Hope this helps.
