I added a new ticket type, will the Form automatically apply?

No, you have to go into the Apply section of Forms to add any new ticket types

I had tickets sold before I added a Form, where is that information?

Information can not be captured retro-actively 

Where do I see the information collected?

To review form submissions, go to Records and set the filter to the event(s) you are looking for. Cick the Download icon in the upper right corner of the screen to download either the Orders or Tickets CSV, based on if your form is set to appear on the order or ticket level.
