If you are looking for a free and easy to use solution for you or your clients to manage a web site, I suggest you to try PageLime. PageLime is a remote Content Management System that allows you to manage web sites update the content, images, and documents without installing any software and only using CSS classes to mark which areas of your site are editable.
After creating your account, you have to register the web site you want to manage and mark up editable areas using the class cms-editable (you can also use a custom name for this class). In this way, you or your clients will be able to modify all marked areas using the PageLime WYSIWYG editor, without modify directly the HTML code of your pages. For example, if you want to make an header editable via PageLime you can use this code:
<h1 id="heading"" class="cms-editable">Your Editable Title Here</h1>Once you’re done with your edits, you can publish your pages with a simple click. PageLime is free, very easy to use and is an interesting alternative to other similar stand-alone applications. Here is a five minutes videos that illustrates more in detail how PageLime works.

Hey this is Tom from PageLime. 3 Notes.
1. The code in the article would need a unique ID to work:
<h1 id="header" class="cms-editable">Your Editable Title Here</h1>2. This is a real solid writeup nice job Antonio!
3. @Ethan while we have a similar integration…we are nothing like cushy in our presentation, no forms, full image editing, templating, in page editing, no page adding, everything works magically, we even handle page includes across most major coding languages with full versioning and content history. If you’re still using Cushy your clients aren’t getting their best from you.
If anyone has any questions feel free to email me directly to tom[at]pagelime.com. I sit here all day writing personal welcome emails, and handling questions. Have a Limetastic day!!
