When you purchase a CKEditor for Drupal license, you are granted one year of dedicated e-mail support. Use your private token (that is issued on purchase) to contact the support channel. Our team of QA engineers and developers will help you with the installation or configuration process and will be happy to answer all questions that you may have.
When your access to the support channel expires after a year, you can renew your CKEditor for Drupal license for a discounted price in order to continue to use the expertise of CKEditor developers. Go to the official CKEditor for Drupal page and scroll to the Renew section for all renewal options.
If you are interested in contacting fellow CKEditor developers and users and would like to share your thoughts on all things around CKEditor and CKFinder, you are most welcome to use the CKSource community forum.
