Web Builder Express gives you tools that help you keep a consistent look, while still giving flexibility to the people who post data to your site. Many other content management systems give everyone complete freedom to design pages however they wish - to the detriment of your site. With Web Builder Express, you can still have complete freedom, but you can also limit the look of your pages to make sure they are consistent.
Consistency is critical to a well-designed site. If you have five people posting data to your site, and each one posts information differently, your site will be inconsistent and confusing to your visitors. Web Builder Express allows you to have great flexibility, but you can also make sure that the people who post data to your site do so in a consistent way.
