If you have ever ordered something online, there should be no surprises here. Basically, all you will be doing in Websites to Go is building up the framework for your site. Websites to Go isn't going to ask you to fill in all the content for your Web site right now. Websites to Go will ask you some questions about you, determine what sort of items you need for your site, and then determine what sort of design and layout you want. Websites to Go is only intended to get you started with developing a Web site.

If you are comfortable with handling all of your Web needs, you would probably find Websites to Go too restrictive anyway. But there are some limitations, nonetheless.
