I maintain a static website for a municipality and have been told to look into a FREE CMS. The more I read, the more confused I get. My web server is IIS on Windows2000 server. If I go with something with a PHP programming language, does this mean I will have to learn PHP? I didn't even know PHP was a language until recently. I know some HTML from using Dreamweaver on the static pages.
Like I said, I am totally confused and ANY advice/help will be greatly appreciated.
