UPDATES (Nov 6 2006) -
Please try to refrain from helping people unless you're completely sure that you're right. Don't risk telling people wrong stuff. If you would still like to try and help, please say that you are not completely sure in your posts.
ALSO
Please keep this in mind when asking for English -> Korean translations:
QUOTE
You need to include who you're talking to because Korean has ways of speaking accordingly since it's an honorific/contextual language.
From now on, I (and I ask others to do the same) won't translate English to Korean unless people state who they're talking to and/or what it's for... simply because I don't want to translate something too formally, too casually, etc and make you sound disrespectful or plain weird.
Examples:
"I am talking to a close friend that is the same age as me."
"This is to my uncle (who is married to my mother's sister.)"
"I am writing this on a message board to all the people there."
"This is for my grandmother."
"I am speaking to someone I'm not very familiar with. She is only a year older than me."
Etc.
Be as specific as possible. Korean is VERY picky when it comes to stuff like this.
