Hello.
I am Richard(Yun, Joo-seong) who took your class and said that "my computer went down all of a sudden"
Fortunately, My friend fixed it up with me so I can use it now.
But I am in the trouble again.
The problem I have is how I do my home work.

I put the CD included in my textbook into my cd-rom and then something appeared on my computer screen.
There were 5 parts; Grammar, Vocabulary, Interactaction, Progress, My test.
And shortly after that, I was confused because I didn't know the way I do my home work.
And then I inquired of some students in your class about the way But they also wondered about that.

I'm really sorry to repeatedly have bothered you but Could you give me a reply e-mail please?

Thank you.

Best regards
Yun, Joo-seong

리차드는 외국인 교수님이 닉네임으로 지어준거구요-_-;;  맺음말로 신시얼리 할려다가 걍 너무 딱딱한거 같아서 Best regards를 썻구요.(사실 맺음말 뉘앙스도 잘 모르지만요..)
