On March 7, 2011 our old osCommerce site was removed and replaced with an entirely new web site created with software from WordPress.org.
Our last major web site change was in 2004, when we installed osCommerce software. While that site worked well and had over 100 pages of content, security problems with osCommerce and challenges with updating the site necessitated a change.
We chose WordPress because it is a simpler system that is optimized for static pages and frequent posts. Other content management systems try to offer too many features and complexity, but WordPress keeps it simple. For advanced features, WordPress has a extensive collection of plug-in programs that extend its capability, and the separate theme support allows us to change designs without re-creating the content.
