i wanna make a friend with students who is trying to learn mandarin

Umm...i am chinese so my mandarin must be well. and what i want is to find a young student like me--i don't want to find a perfessional teacher for now(because i am still not be famliar with this site), and what's more i am so willing to teach you mandarin. i think, as youth, we can not only teach each other language, but also we can exchang the idea or info about our life. THAT must be a good way to get close to the country you like. SOOOoo...WISH U TO MAKE A PROGRESS WITH ME~btw, i found some of you can send the message via mobile, i want to know how to make it.(iis that  a app or just website)
