If your username is chng, then your home directory or "tilde" directory is indeed /home/chng
But that's not where web pages go. That directory contains all sorts of configuration information that you do not want published to the entire world, for the sake of security if nothing else.
On the web adminstration panel, click on "Manage" under "Domains" The page that appears will show each of your domains separately. In the column headed "Service Type", go down to "Web" and then across to the sixth column ("Modify") and click "Edit"
On the page that appears, under the radiobutton that says "A fully hosted domain", there should be a line that says "Web Directory: /home/", then "chng" in a select box, then "/", then a text input field with (probably) something like "www.yourdirectory.com" or "public_html" in it.
Your Web Directory (also known as your "htdocs" directory) is where "index.html" would go, for a URL of "http://www.yourdomain.com/index.html". Of course, you can create subdirectories of that directory, which would be reflected in the URL accordingly.
Does this answer your question?
