In the course of managing several hundred websites, we've seen it all when it comes to domains. We've also seen that many business owners aren't aware of the dangers of not understanding basic domain information.
At JAM, every website we build uses our custom-built content management system. A CMS is the application that allows for publishing, modifying, organizing and deleting content on a website. To access the CMS, a user types in the URL of their website, followed by a specific subdirectory (like "/admin-login") for example. From there, the user enters their username and password and is granted access into the "back-end" of the site. Once logged in, the user can make whatever modifications they need to make. Every website has a CMS. The three most common are Wordpress, Joomla, and Drupal. Together, these three account for more than 70% of the CMS market.
