My search so far:
First search lead me to this thread:
Suggesting that this is Stargirl. (but probably not)
I also came across this article ( http://www.sk-gaming.com/content/30970-GSL_Ro64_Days_1_and_2_interviews ) that contains the sentence
"I practiced TvT with Jeon Yong Su who uses the ID Seo Yeon Ji on battle.net."
Is Jeon Yong Su a mis-spelling of Jeon Yong Soo aka LotzePrime or is it a different person?
The reason I'm trying to figure this all out is that there's a new replay I'd like to cast that involves this person and I want to make sure I've got my names right.
Help me, Obi-Wan-TL community! You're my only hope!
