Brilliant, thanks for your reply Chuck S. Just to make absolutely sure I don't void my license, what you are saying is that I can set up a test install on
www.urltest.com (which is not publicly available), and also
www.liveurl.com (which is publicly available) and this won't affect this checking system that is in place?
Hopefully you won't be receiving a grovelling email from me after I manage to accidentally get myself locked out for a license violation!
