The aim of CMS Made Simple is to supply a simple and effective way of managing content of primarily static sites. Before you can ask why you need a content management system for a site that doesnt change its content, let me tell you.
There are tons of content management systems out there but they are basically all the same. Other CMS systems are great if you have a lot of news or articles on your site, but what if your site content doesnt change a lot, or only small parts of it change? Doesnt make a lot of sense to create a new entry in your blog style site just for a simple update, and whats the point of having time stamped blog entries if you are constantly updating them? Voila, in comes CMS Made Simple.
CMS lets you update your pages and keep the content on a static page that will not become stale regardless of how much other content gets placed on your site, unlike a blog style site where entries get pushed off the page and your users have to check the archives or know an obscure link to get to the original story.
