Isn't RC Mushroom in Hong Kong? If so, it may be hard for them to translate or understand your english. Just a though. It's not like everyone speaks english in the world. I work with several people from Hong Kong, and though it may seem they speak and read good english, there is still alot they don't understand. I think one thing here is communication. Blah blah blah... hehe But at least you got it cleared now.
