Wangyushi,
I wanted to join in the chorus of thanks for your efforts and to further extend your already hearty welcome at CFC!
Although I generally try to speak only for myself, I know that many of us -- especially some of those who have already posted (and whose language skills I am envious of!) -- have long thought that all of Civ was far too centered on European history and culture.
Your joining us -- by definition, helping us in these efforts -- is extremely appreciated, and your presence very welcome. -- Do not be shy to ask for assistance in return!
Again, welcome.
Best Regards,
Oz
