Emanuela,

Yes, I'd be interested in knowing more about it too. In the US more and more parents are taking their children out of public schools and "home schooling" them, using a system originally developed in Australia for the same reason as were radio classes: long distances.

Also, a friend is getting her master's degree in astronomy via the internet. It's offered by a university in Australia.

And if you need any help in translating Helen of Troy's post, just let me know
