Dave's ESL Cafe is a place where English teachers living in Korea gather to chat. The url is http://www.eslcafe.com/forums/korea It's not easy to sign up but it's worth it.
You can register by clicking here and then following the instructions. After you finish you will have to send Dave an email explaining why you want to join. Although considered an invasion of privacy by many, worried about the large amount of personal information requested, this is apparently just a rubber stamp formality.
Dave's ESL Cafe is a professional site with advertisements which means that certain things aren't allowed, and there is a swear filter as well. Some people consider the moderator policies to be heavy-handed and have fled to other places, or have been banned, including former moderators. Many former users now frequent David's ELT World Forums.
