Well, when I was with ATEK, one of the things I wanted to do was create an useful guide to Korea.
But that didn't happen.
So if you go to the top of my page and click where it says "Expat Life" you can see a (still in progress) page with some of the links I think are most useful to somebody trying to get themselves sorted in Korea.
One section I like is my "places to learn Korean" link list.
Hangul (writing system)
Comparative reviews of "Study Korean" books
Learn Korean Online
Korean Class 101's Youtube Channel
Sogang's online Korean Course comes highly recommended
Recommended by I'm No Picasso: Learn Korean Now
Recommended by Roboseyo: Korean Class 101
More complete list of learning Korean resources
For the rest... if you run/know about a page you think deserves a link on my page, send me an e-mail at roboseyo at gmail, or put a link in the comment.
To the guy who's been getting his comments deleted: no. Links on where people can find an Indian wife (prefaced by a paragraph of shit-talking about western and Korean women) don't qualify.
