Welcome Christine, stand back and take a deep breath as a load of blokes here will jump in and offer you all sorts of assistance. You will need a towel to wipe up the drool but that is just the way they are, nice, friendly, dribbling sort of fellas. HumanBeing has posted a good way to get the d/l sorted if my google translation worked (lots of fruit involved). You speak Mandarin so the original will make sense ot you I guess.
to get an idea of what is current for different purposes, please have a look at ChinaV's threads:
