Wysiwyg editors?

Hello, Once again no PHP question... If I want to allow users to design and create their own static pages and store them to a server as a part of larger site what ways I have to do this? I once tested htmlarea (http://www.htmlarea.com/) and I think thats something I'm looking for. I don't have time or skills to do the editor all by myself so I have to use some already available components. They also should be freeware since it's a non-commercial site and I'm doing this as a hobby. I think there's no free version of htmlarea anymore? First of all. In the htmlareas site there's a comment: "Both Mozilla (includes FireFox) and Internet Explorer include a way to make sections of a page editable. IE has the MSHTML Editing Platform, and Mozilla has Midas." So what about Opera? Are there wysiwyg editors for Opera? The one time I tested Htmlarea it only worked on IE. Second. What are the ways to store user created pages? Just dump all the code the editor outputs to database? Or are there other options? Thank You -Will
