You were looking for me on Skype, Hyunwoo? And I missed out. Actually I stopped logging in because I couldn't find anyone else on it!
I will make a point to log on Skype more now so I can have the world's best Korean help I usually can log on between 9 am and 12 pm my time (US mountain/western time), but that is very late night for you. (We are 16 hours apart.) There are other times I can occasionally log on though. We'll catch up with each other at some point!
