Ok.... I tried to look up the names you asked for....
I got an exact match for Manabu Oka... The email address is mo18@cornell.edu
The other two, I could not get exact matches....
But, well, I narrowed down to three choices each.
For Jin Lee (I think I might know him... freshman, you said, right?)
I got three matches.....
Sung Jin Lee -- sl27@cornell.edu
Jin Il Lee -- jil3@cornell.edu
Ginny Jin Lee -- gjl2@cornell.edu (I doubt this one)
And for Yoony... I couldn't get any matches, so I looked up Yoon Lee, and I
got....
Sonia Yoon Lee -- syl1@cornell.edu
Yoon Ji Lee -- yl18@cornell.edu
Yoon Lee -- yl28@cornell.edu (Hmm... maybe this one?)
I hope you find the person you're looking for.
If you need any more help, you can email me to jcp2@cornell.edu
And you can call me Tivor... most people I know over email call me that
anyways... =)
Well, take care and enjoy life~~
Tivor
