What an incredible activity under the post!
Well, I’d like to offer my help with English as well. In exchange for help with Japanese of course ;)
I’d be happy to discuss anything in English. As for Japanese, I’d be very grateful for correction of my sentences.
Talking during a call (Skype?) is the best way to practice, so that would be the best option! Finding a common topic is important, though a bit tough, so it would be very handy to use ESL Discussions.
If you’re interested, please chat me in private messages. Looking forward to productive language exchange :)
