Whizzywig rich text editor lets people create rich, formatted text through a web form. It actually creates HTML (or xhtml, if you prefer) but you need no HTML knowledge to use it.

If you can use a word processor or email, then you can use this. Whizzywig is cross-browser: it is written in Javascript, which will run in nearly all web browsers.

Features:

-Fully configurable toolbar: as many or few controls as you want, you choose the order, even the color
-can be translated into other languages - see this Spanish version  OR GERMAN VERSION.
-can generate valid xhtml
-Attach your own stylesheet, so the editor output matches your site style - see customizing Whizzywig
-Small - just over 20k of Javascript (but similar features to editors 5 times this size)
-Fast - Small and light weight and avoids pop-ups: no round trips to web server during editing
-Easy to install - just one javascript file - no extra files for dialogs
-Use text buttons, the graphic buttons supplied or create your own
