The site uses a simple mp3 player to deliver audio-only material.
When you make your selection from the menu, you will be presented with a list of the mp3 files associated with that choice.
The site is written to be accessed by most modern browsers. I test it using Chrome and Firefox, and these are my preferred browsers.
Absolutely not. The site is entirely non-commercial and contains no adverts or other revenue-generating content. It is funded entirely from my own pocket.
