You don't have to have kids to benefit from this...

There are many, many websites that feature information on working from home, how to get started, etc, etc.
Now, I don't have kids, but the first website I stumbled upon for info on working at home was www.wahm.com. In case you don't know, "wahm" stands for work at home mom. You don't have to have kids to benefit from the site. Trust me, I have gained tons of information by visiting the message board there. If you have never visited the site, I highly reccomend you check them out.
