If you wanna help out a teacher who's trying to make school interesting for his students: Just write a comment that you'd like to take part and which country you're from! You should understand some basic english but if you can understand my text that will be more than enough. The students are at a level where they can talk about everyday stuff but not more complex things. And of course it would help if you're about the same age (12-16) as them. Also if you know someone, have children, etc. who'd like to join: everyone's welcome!
So whether you're from the US, from Great Brittain, brasil, australia, india or somewhere completly else: I'd be happy to hear from you! I believe in the goods that reddit can do for our society.
TLDR: If you're interested in cultural exchange through video conference, e-mails or something else leave a comment. I want to link up my students with people from around the world.
