Google 101 Gmail- Translation Features

I would like to use the translation features within Gmail to communicate with parents in different languages. I am an ESL and Spanish teacher so this feature will be extremely helpful for me in the classroom. I also love the idea of having pen pals and I plan to do some research to try and find a teacher in Spain and organize pen pals through gmail with my students. All of my MS and HS students have gmail so I am really excited to try the pen pal idea out. I think my students will love it!
