My girlfriend uses it. Its a simple program which she downloaded from the net. If you are asking how to use it, Well its simple, If you want to type a chinese word then you have to know how it sounds like, for example you want to type Wa(means I in chinese) then you type WA and the program will show you a list of chinese words to choose from, if you know which it is, you just pick it and then type the next word and so on...
