I am working on adding webforms to a microsite. The form is added but is appended with authoring information like - Submitted by User on Sun, 03/30/2008 – 13:20.” at the top of the page.
To hide the display of this authoring information:
Goto Administration > Structure > Content Types > Webform and select edit > Goto display settings tab and un check ‘Display author and date information.’
And you can get rid of the author information on your Webform.
