What exactly does SSH Shell do? Can I publish web pages with it instead of using FrontPage or Dream weaver?

SSH stands for Secure Shell. SSH is a remote command line (in the Unix world this would be the shell) program. It is like telnet, which gives you access to a command line on another system over a network, but SSH uses encrypted traffic and is focused on being secure in general. The unoffocial FAQ is here. Now, SSH requires a client and a server. The server is waiting for a client to connect with it to begin an encrypted session. In that session, the client can run commands, like copying files over to the server's computer (like FTP - in fact there is an sftp). So, if your webhost provides you with SSH access, you can connect and transfer files to your web host (the equivalent of publishing in a WYSIWYG editor). There are also subset commands which use SSH to perform tasks. There is sftp and scp (secure copy), for example. These only give you specific functionality, not a whole command line to work in. There are a few graphical SSH clients, most of which are commerical. Refer to the FAQ for options on Windows.
