Some clients want to self manage the text and images on their website. The Joomla content management system gives you that opportunity. You can change the pages from any computer in the world and you can do this without any experience or skills in the field of web design. It is similar to editing a Word document.
The advantage of in-house site management is that you can keep your site up to date without having to wait for your webmaster. You could also choose to do the simple alterations yourself and leave the more complicated changes to your webdesign studio or webmaster.
