WYSIWYG editor to change textarea

Hi all, I have been looking to implement a WYSIWYG editor that will automatically transform a <textarea> into a Rich text area / WYSIWYG. We have lots of dynamic content that is pulled from a database and files. Therefore we cant really change the <textarea> field. I have tried the tinyMCE but its causing conflicts with some existing JS code that cant really be rewritten. A lot of other editors actually generate the rich text area in a strange way and don't use the <textarea> field at all. Are there any editors that you people will know of that operate in a similar way to tinyMCE, IE you include the JS in your head and it will change all the textarea fields to rich text areas? Thanks in advance. http://www.elemental.co.za http://www.wapit.co.za
