I stumbled upon the Korean Wiki Project a while ago and I thought some might be interested. It's a collaborative Korean language learning effort spearheaded by a fellow KC101er who made online headlines a while back over at the Hub of Sparkle.
My favorite page found so far has got to be the internet and text messaging page that has a really cute clip from a Korean drama explaining the confusing nature of text messages. If you want to learn about Korean chatting and text lingo, this page is a nice starting point. If nothing else, one of the clips embedded will make you smile.
