Free way for clients to eidt their own html text?

Hey All,

I’m trying to find a program that (is preferably free, but I’m open to suggestions) will allow my clients to log onto a specific page, and edit their own text via a WYSIWYG type of web-based interface?

Any ideas? Basically, I have very simple HTML text, and a client wants to be able to update it on their own. I’m not sure the best way to accomplish this.

Thanks!
