Ben,
You seem to be everywhere.... I installed the jquery and activated the ckeditor. I like it very much with geeklog but I cannot upload any pictures. I get the following error: "The file browser is disabled for security reasons. Please contact your system administrator and check the CKFinder configuration file." Help!!!

By default CKfinder stores images in your public_html/images/ckfinder/userfiles/. Make sure those folders exist and are writable.
Maybe you will also need to create a _thumbs and a images folder under the userfiles folder.

Ben
