Instead of a static site you can install Wordpress, change it to look like a static site, and benefit by all its features and plugins. I just tried an example and it works wonderfully.
You can follow this simple 6 step guide to upgrade a static site with a wordpress based equivalent.
1: Download and install WordpressDownload the latest Wordpress version and read the 5 minute
install guide.
You will need to have an available mySQL database and to upload the Wordpress files to your webserver. Then you point your browser to the server, fill the installation form with the database details and click install.
2: Select and install a Wordpress theme.There are hundreds of themes available. At
themes.wordpress.net you can view the themes by thumbnail and test drive the ones you like. Once you locate the one you prefer you must download it and upload it on the webserver under the directory :
/wp-content/themesTo enable the theme, use the Wordpress admin screen and go to Presentation->Themes. The new theme should be available to enable.
3: Install the plugin Filosofos. Filosofos makes changing the normal Wordpress blog-based view to a static view very easy.
Download the plugin, upload it to the plugins folder in wordpress, (/wp-content/plugins) and activate it by going to the plugins admin menu. Go to Options-> Home Page Control and change the home page to a static wordpress page. To make a Wordpress Page you select Write Page rather than Post.
