domain name

If I register a name at godaddy.com and then use that when I get a server at powweb.com will I be able to have theregisteredname.net/whateverfolders/blah.html or whatever? It's not the kind of domain where all the pages on the server is theregisteredname.net like name.tk is?

exactly you can call the pages what you would like and they will show up as yourdomain.com/filename/pagename.html in the window - unless you configure it otherwise, thats how it will work
