i used the following code to use fckeditor:
</script><script type="text/javascript" src="fckeditor/fckeditor.js"></script> <script type="text/javascript"> window.onload = function() { var oFCKeditor = new FCKeditor( 'message' ) ; oFCKeditor.BasePath = "/forum/fckeditor/" ; oFCKeditor.Width = 1000 ; oFCKeditor.Height = 500 ; oFCKeditor.ReplaceTextarea() ; } </script>
