I've collected some websites that helped me learn Korean... I'm posting it on here and hopefully it would help you guys out too I dont know what level you guys are at... But I'm still a beginner. Just learned the alphabet, some basic phrases... but these websites are a big help
Introduction to Korean
http://langintro.com/kintro/index.htm
ZKorean
http://www.zkorean.com/index.shtml
(this website has an electronic dictionary. It's simple but helpful. It has the alphabet plus audio to help you know how each letter is pronounced. Explanation of the grammar and most importantly an overview of South Korea.)
Learn Korean
http://www.learn-korean.net/forums.html
(One of the BEST sites I've come across. I highly recommend it to all the newbies and beginners.)
Google Translate
http://www.google.com/translate_t
(Quite helpful if you want to understand what's written, if you have a long paragraph and you're struggling with a lot of unfamiliar words, then this would help you out. However, it's not precise. It gives you the literal translation and isnt grammatically correct. This will help you UNDERSTAND... But dont rely on it to form sentences.)
