Thanks for the reply.
Creating folders in Dreamweaver works fine.
The WordPress install, however -- not so much. I installed it into a folder I'd created for it, and the installer filled it up quite nicely. Problem is, a whole bunch of links in the PHP files are busted. They're basically looking for WordPress to be in the root folder of the domain.
So none of the admin stuff works at all.
Meanwhile, I also can't get my css stylesheet to work, though the link to it's in my index file.
And when I telnet to my site, I get kicked off after I give my login name and password with a message saying "this account allows only ftp connections".
So I'm feeling fairly frustrated all around.
