This question is regarding SharePoint Online 2013.
I have a team site setup with a custom list. I want to have a "thank you" or some sort of a confirmation page show up after the user has submitted a list item. Instead of taking the user to the list screen (from which they came), when adding a new item, I would like them to get a thank you page instead. I am familiar with using SharePoint Designer and I am sure that this will require its use.
