I have a SharePoint blog where few people can contribute but everyone can comment. But they want to comment as anonymous. So I created a new column in Comments list called "Post as anonymous" with a check box value (Boolean value). Now, based on the check box value I want to change the "Created by" to "Anonymous" in Comments web part so that people cannot see the real commenter.
I tried to accomplish this by designing a Workflow in SP designer. But it turns out that there is no "Created By" in "Set field as" action.
Is there any way to accomplish commenting anonymously? without a third party application.
