Google Sites have certain limitations.
Clicking on images enlarges them but to return to the page click the BACK button. Clicking on the X at top right closes the whole site.
Some pages may not display properly at lower resolutions or on small screen tablets and iPads.
The site is regularly maintained and the date of the last update is shown at the bottom of the side bar. Important updates will involve the details of the latest play but minor updates may only include minor layout adjustments or text editing.
The site is found by all the search engines, including image searches.
