Although I don't play on the Chinese WoW servers, I have actually installed the Taiwanese client on an American server so I can further my study of Chinese while still talking with my friends I've already made on WoW.
I have one quiiiiick question, for anyone who may know - is there any possible way to get English profession or item links to show up in chat and macros? My lack of ability to link my professions or item drops is the only thing that's preventing me from truly being able to make the switch over to the Chinese client and never look back.
