Oh nice, a few days ago I thought it would be fun to be able to play this old game again. And then I found this thread.
I never played on any of the other private servers, quit shortly before webzen killed off the game back then. But this sounds promising so far.
I will download and play a little when it's ready. At least until everyone runs around full party buffed and in boring, perfect bought equipment...
Good luck with this project!
