I love Skype! It is the best invention in telecommunication ever! I keep in touch with my family in Brazil for free! In the classroom, you can have students exchange information with one another and telecommunicate with people around the world!
This website is so cool! You tell the website what language you speak and what language you want to learn and it connects you with people around the world who will help you learn that language. It gives you all their information including skype ID, yahoo, MSN, etc.
