A bit of background info before I get down to my question - I'm using the URL method of loading modules to Drupal as I do not wish to save them to my dinosaur age PC. I have also not uploaded Drupal to my PC, but am operating it via Pantheon. This is not only because of my old PC, but as I am only in the very early stages of developing my website, one advisor has said I don't need to worry about that and other programs such as MySQL.
I'm keen to get CKEditor onto my Drupal platform, so have added the CKEditor - WYSIWYG HTML editor module and this appears so far to be successful.
The tutorial I am following assumes that I am able to save the CKEditor program to my PC... which I guess in essence I can, but I am hoping there is a way to avoid doing this and load it the same way I do a module via URL perhaps?
