CKEditor requires JavaScript to run. In a browser with no JavaScript support, like yours, you should still see the contents (HTML data) and you should be able to edit it normally, without a rich editor interface.
Don't know HTML? That's ok - use this tool to generate your HTML. It's as easy as using a word processor. Simply type your text, use various tools in the toolbar for positioning and styling, even add images and when done just click on the 'Source' button below and your creation will instantly turn into HTML. Highlight it all (by pressing ctrl-A), copy it (by pressing ctrl-C) and then paste it (by pressing ctrl-V) into any web page or blog. Presto! Instant HTML without knowing HTML!
