It is BrainStorm's best practice to keep all content created in QuickHelp, unpublishing the content rather than removing them. This allows organizations to retain the usage data associated with each asset.
However, if content was created erroneously, or incorrectly, please, enter a Support Ticket. Include the name of the content that is to be removed (include the Topic and Category names). Please allow up to 3 business days for this to be completed.
