There's a lot of websites online that help you create your own. You can also pick up the book "Building a Website for Dummies" 2nd edition. Those books are always helpful. You can enroll into a computer class which will go through all the steps in order for you to start.
I've read the posts from this thread and I'm interested in building a website. I'm not familiar with the programs you have mentioned and I would like to use something that does not require too much computer knowledge. I want my own domain name and I want to be able to manage my website online, no mater what computer I use. What do you recommend?
