Submit an Anonymous Question During a Webcast Event
Anonymous questions are posted by making sure the Post Anonymously checkbox is selected when submitting your question in the Q&A interface. This will ensure that the Event Admin and Event Moderators will not be able to view which user account submitted the question.
You may only ask anonymous questions in the Q&A interface. The Chat interface is always associated to your user account.
 
Tip: All questions that are made public are done so anonymously. Your user account name is not associated to the question on the Group Questions tab.
