Here are some internet resources that you can use to learn, or review, Italian. All of the sites have some free content, but there is content you can pay for as well.
http://italianpod.com/ (This is a good site--I subscribed for a few months and listened to their podcasts, but there's some free content available as well.)
http://www.bbc.co.uk/languages/italian/ (This is a site put together by the BBC in England; it has some nice resources.)
If you find other good resources, please share them with the group!
