When you want to have a direct communication with your friends or colleagues abroad. Instant chat tools such as MSN or QQ are very convenient ways for you to send messages, do instant communication, send files or have an online dialogue.
As they may have no idea how to register and how to use the QQ, and they can't read Chinese tutorial, and I can't find the HELP on the web http://www.imqq.com/ either, I prepared a simple PPT (also a PDF file) on how to register and use QQ in English. If it's of any help to others, I'll be greatly pleased.
P.S. After trying for several times, one colleague abroad can finally use the QQ, and I have obtained the files he sent. He said this software is great, he would recommend it to his friends and colleagues.
