These are resources I recommend when thinking about a simple site. Make sure you look at the links so you have an idea of formats and other options. Remember, in this case, the most important thing is about the structure and not the color/type. The latter are easily edited in the CSS, the former are more difficult unless you understand CSS and modules.
Joomla!
Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.
WordPress
Takes seconds, costs nada. You can get a blog started in less time than it takes you to read this sentence. All you need is an email address. You’ll get your own WordPress.com address (like you.wordpress.com), a selection of great free and customizable designs for your blog (we call them themes), 3 gigabytes of file storage (that’s about 2,500 pictures!) and all the other great features listed here. You can blog as much as you want for free, your blog can be public to the world or private for just your friends, and our premium features are completely optional.
