page editor in flash or ajax.

I have a community site that the user can write a presentation of himself, right now its with some html codes and its hard for manny members. Therfor i want this made. a wysiwyg editor for the textarea. you should be abel to press "add text" and so on and it will be dragabel so that its shown exactly wher you wanted it. you should also be abel to put images under like backgrounds and then add text on top of that. i guess the best way would be flash in some way so it loads a swf file as presentation or something like that. got anny questions please write to me!
