I built my site with Drupal. or D7 It is a CMS like other popular formats like Joomula, and Word Press and a few others.
I am a D7 fan but it is not web builder.
Feel free to review my site. link in sig below. Just know I am working on the back office side, later I will hire a proof writer and copywriter to assist.
