Can you write all in Korean? There is a study group of intermediates that has an "all Korean" policy. I joined, but at this point it is so over my head. I am mute there. haha If there is someone who is comfy with Korean and wants to join, check out https://www.facebook.com/groups/Korean2014/?fref=nf These people are from Korean Digital Academy.
