Second life is an online virtual world where players can get together to chat, play games, buy clothes, even attend real-life schools. Second Life currently has over 8,000,000 online "residents", 1,548,131 of which have logged on in the past two months.
Second Life also has its own currency, called the Linden, which players can exchange for 3D products such as clothes, jewelry, weapons, and more. Almost anything you can buy in real life is being sold in Second Life.
The current Linden exchange rate is 240 Lindens per 1 US Dollar. Most clothes and smaller products sell at about that price, although depending on where you shop, prices can rage from 1L - 2,000L.
Although it's not guaranteed that you will make money owning a store in Second Life, there are people who have been successful. Jennifer Grinnell, owner of the store Mischief, quit her job as a dispatcher when she began to make more from her virtual store than she did at her full time job. You can read more about it in Wired Magazine. There have also been many others who found success owning virtual stores, including companies such as T-Mobile, Sony Ericsson, and Playboy.
You need to have a basic understanding of graphic design before creating items in Second Life, but being an expert isn't required. Secondlife.com has free modifiable templates to start you off, and you can buy modifiable textures in many stores.
If you are interested in owning a store without doing graphic design, there are warehouses in Second Life that sell bulk items which can be modified, transfered, and copied.
SLexchange.com lists items like these and more.
Creativity is one of the most important aspects of being a designer and store owner in Second Life. There are hundreds of stores that buyers can choose from. You should have an original idea that will make you stand out from the rest. If you can get people talking the money will follow.
Second Life Insider is a blog that discusses everything that is happening in Second Life. While not business-oriented, I recommend reading it because it will give you an idea of what is popular in SL and what buyers are looking for.
There are plenty of ways to make money online, and you can even pay off
credit card debt in the process. Many people will look for a
low interest credit card if they're not able to
pay off their charges quickly, and
student credit cards are a great option. If you're
charging more than you're making, maybe you should try a Second Life shop!
