@Barnez - I tried that method - created the subdomain at Afraid.com as instructed, but inserting it into the code didn't work. Had to go back to using my IP address. Also, note that his code has one tiny error in it - there should be no space in Order Deny,_Allow - leaving a space after the comma gives an error when just accessing your home page.
I've written to the author and if I get it figured out, I'll post more info here.
