QQ is the name of an Instant Messenger program very popular in China. It has over 500 million members, which is almost twice the population of the United States. Most people in China use QQ for instant messaging. QQ also has other features like file transfers and a translator which enables chatting with people in different languages. I downloaded the installation program after waiting a long time for the QQ home page to load and thought I should post the direct QQ download link below.
After downloading and installing the program, you can sign-up for your QQ number, which is a 10-digit number used to sign into the program.
