Teaching Idea: Have an authentic communication all over the world using Interpals

Have you ever heard about interpals? I my self is newbie on the site. I made the account about three weeks ago and discover many things. It's is the premiere online community for meeting penpals, language partners, travel buddies or just plain old fashioned friends. What is penpals? A penpal is a new friend from another corner of the earth whom you get to know through letters, online messages and chat.
Since it member is people from all over the world, it would be really useful site to practice talking in english. You can even choose with whom you wanna be friends by giving checklist on the area. Sometimes there are people using fake profile, but some others are there for decent friendship. It is an excellent site for practice language as there is session called language exchange. You can have a chat directly with native and any other english speaker all over the world in real time. Be wary of scammers, perverted, or spammers. I have experience finding some of them on the site, but you can block them right away. Report them and their account will be deleted in an instant.
Somehow, through this experience I want to apply this site to my teaching practice. I just hope students will have an authentic communication and enhance their speaking and writing ability. Beside, it will broaden their horizon by understanding other countries culture or the people different mindset. Wanna have penpal? make your account at http://www.interpals.net/.
