Make Wysiwyg Use CKEditor CDN Is it possible to make the Wysiwyg module use the CKEditor's CDN for delivering the editor to the browser client?
If all you're using the wysiwyg editor is for ckeditor, you can use the ckeditor module instead.


  This module will allow Drupal to replace textarea fields with the
  CKEditor - a visual HTML editor, usually called a WYSIWYG editor. This

  doesn't require any kind of installation on the client computer.
