The instructions don't tell much on how to do this.  I uploaded the contents of the "Web" folder to my server in a root folder called "/chat2/, and had the host run the sql scripts, and create a virtual directory pointing to /chat2.  I can't find any documentation anywhere that tells where all I need to adjust the connections strings.  I changed it in the web.config file, but that doesn't seem to be enough, because it still doesn't work.
