I do not want to have in the footer of the form "form created by Lawrence Sam."
Hi Lawrence, the footer cannot be removed, but you can customize the footer text.
Login to Formfacade. Click on the form to open it. Edit page will be displayed. In the Edit page, click on the profile name in the top right corner. Click Change theme. Theme settings page will be displayed in the Preview page. Click Page. Enter the required text in the Footer option (replaces "This site belongs to...") and click Save.
