Sorry about the ads. I will see what I can do. I originally introduced Google ads to try to cover the cost of the domain and hosting, and the ads were unobtrusive and down the side of the page where you could ignore them. Now Google have started doing pop-ups without telling me they were going to do it. I certainly didn't ask for them and I will see if we can go back the way we were.
When I go onto the site myself, I usually get a pop up - but usually only once and I just close it and it doesn't come back.
