Now, you have to download the software, free of charge, and install it. It's about 67mb of data, and it shouldn't take very long at all; just make sure that you have the proper system requirements, especially the right video card. After that, you are ready to start enjoying your Second Life. You can do all kinds of things, but it might be a good idea to start with customizing your own appearance. There's quite an in-depth 3D rendering program for your character, so the facial features can get pretty subtle if you take the time for it. Also, you can socialize with your fellow Second Life users and go to nightclubs or go and gamble. There are a wide variety of options available to you, so do whatever suits you. If you have any additional questions, check out the main Second Life page. There's a comprehensive FAQ section, and a phone number for any questions Monday through Friday, 9am-6pm PST. You can also find more information at http://lindenlab.com/, the website of the company responsible for Second Life.
