Can anyone suggest a free wysiwyg editor that will work with HTML and or PHP, like what you have when you use yahoo mail or something like that, that I can use so that people can submit rich text in a form on a webpage? I'd like it to be platform/browser-independent if possible, and to be valid (x)html. If anyone can suggest anything or write something, I'd appreciate it. Thanks.

Thanks, I'll try that out.
